Ok this is what we have done since last time; new service release GTP.NET 3.2.6.6 (stronger than ever!), GTP.NET.SL has been updated for Silverlight3 (This is going to be huge!) the ECO framework version 5 has been released (hurray!). Gaffr.net has been released (Yieppi!). ____May 2009____ Updates to GTP.NET 3.2.5.21; Summer is almost here, we are stuck in different projects but enjoying life. If you are about to prototype something for a new project, involving plexityhide or not I urge you to test Gaffr.net. Model your information with breeze and when you are satisfied you are in control of the problem domain - use ECO ,a framework you will get addicted to faster than crack-cocain (I think, have not really tried; If YOU have tried both let me know, or maybe not...). ____March 2009____ Updates to GTP.NET 3.2.3.17; Z-order link bug, and one nasty bug when using sorted dataviews fixed...

Gantt_ASP, adding hyperlink in the grid Administrator — Tue, 05 Jan 2010 19:11:00 GMT Abstract: Question I want to add a hyperlink "Delete" for each row in the grid Answer Add a extra column that has nothing in the DataSourceColumn: Gantt_ASP1.Gantt.Grid.Columns.AddNew(PlexityHide.GTP.CellType.SingleText); Gantt_ASP1.Gantt.Grid.Columns[1].DataSourceColumn = ""; Then when the row is initiated, inject your callback link: void Grid_OnNodeInserted(Grid aGrid, NodeEventArgs e) { // For each new node we set up databind for subnodes... e.GridNode.SubNodes_DataSource = (e.GridNode.ListItemWhenDataBound() as DataRowView).CreateChildView("subnodes"); string postbackref = "DELETE:" + Gantt_ASP1.GridNodeKey(e.GridNode.GetCell(1).GridNode); string deletecontent = "<a href=\"javascript:" + Page.ClientScript.GetPostBackEventReference(this, postbackref) + "\">Delete</a>"; e.GridNode.GetCell(1).Content.Value = deletecontent; // and for time items GanttRow gr = Gantt.GanttRowFromGridNode(e.GridNode); gr.IncreaseRowHeightOnCollision = true; gr.IncreaseRow_SuggestedHeightPerItem = 20; gr.Layers[0].TimeItemLayout = "spacy"; gr.Layers[0].NameInDS_Identity = "id"; gr.Layers[0].NameInDS_Start = "start"; &n How can i set the Height of gantt_ASP, so that all rows just fit into the gantt-(border) ? Administrator — Sat, 09 May 2009 12:11:00 GMT Abstract: Question I use a gantt in my ASP.NET project: The poperties UseExpandedRowHeights and CollisionDetectionSyncron are set to true, so that my rows have different sizes. How can i set the Height of the gantt, so that all rows just fit into the gantt-(border) ? Answer You will need to load the data, then iterate the rows in Gantt_ASP.Gantt.Grid.GridStructure and sum up the heights. You will need to add the DateScaler height as well. Then set this value as the control height. Update; this code will solve this: protected void Gantt_ASP1_OnClientSideChangesApplied(object sender, EventArgs e) { Gantt_ASP1.Gantt.Grid.Refresh(); Gantt_ASP1.Gantt.TimeItemArea.Refresh(); if Position texts before and and after a time item Administrator — Thu, 09 Apr 2009 14:30:00 GMT Abstract: Question Howto get textblocks to appear before and after the TimeItem? Answer In this time item the Grid with name Rect is the one that gets the size based on Start and Stop datetime values. The Text after the time item is the one named Text1, the one infront is Text2. Text1 is positioned in the event implementation: SizeChanged="TimeItem_SizeChanged" see impl at the bottom Text2 is positioned with a Translate transform with a negative value. <DataTemplate x:Name="SquaredTimeItem"> < Scrollbar for all GanttRows Administrator — Thu, 09 Apr 2009 13:15:00 GMT Abstract: Question I used your toolkit tree view example as a basis for this but I have set the tree view’s height to auto so as to use the whole screen – but now I have lost the scroll bar on the right. Can I have full screen and a toolbar? Answer You can do this many ways I guess. One way: <Question Is there any way to show a background line between the days? Maybe even hours/minutes depending on scale?

Administrator — Tue, 02 Sep 2008 18:49:00 GMT Abstract: Question How to obtain a runtime key for gtp.net? Since my last update of gtp.net i've to call RegisterRuntimeKey... Answer You get the runtime key by visiting this page http://www.plexityhide.nu/runtimekeys/Default.aspx You must enter your serial number (CSGTPXXX) & your exe or assembly name. The exe or assembly name to use is the name of your produced assembly or exe that will call Gantt.RegisterRuntimeKey or Gantt_ASP.RegisterRuntimekey. Do you run a web-project without assemblies? Then you enter the dns name (for this site its plexityhide.nu) of your deploy server instead. You will get an automated email directly on completion of the form with the key + instructions on how to enter it into your application. Need more hints on what to enter in the assembly name box? You can call gantt_Asp1.RuntimeKeyHelp or/and gantt1.RuntimeKeyHelp_Assembly to get the correct info for your application. About runtime keys: Call this early in your application to register the runtime key. The runtime key is free for registered users and is obtained as described at http://www.plexityhide.nu/runtimekeys/Default.aspx The runtime key is unique per application, you can obtain as many runtime keys as you need. The runtime key is NOT a runtime license, registered users have the license, the runtime key only removes the runtime plexityHide marking. The main reasons for the introduction of runtime keys are: #1 To Better understand customer applications and demands to guide us in further devel We are using user drawn links in the Gantt_ASP and it is too hard to the links Administrator — Thu, 03 Jul 2008 19:26:00 GMT Abstract: Question We are using user drawn links in the Gantt_ASP and it is too hard to select the links, especially when they are above TimeItems or have a length of 0. Is there a easy way to get a larger selection area and to have a preference of links above TimeItems? Answer When investigating this we found that the comment on the UserDrawLink was very brief, and we have extended it to this: /// <summary> /// Fired when l how to print multiple page in c# code, GTP.NET ? Administrator — Thu, 03 Jul 2008 18:17:00 GMT Abstract: Question my Question is about GTP.NET component. how to print multiple page on c# code? Answer .NET comes with a very good PrintDocument class. Use this when you want to print the Gantt. You might wonder why we just did not wrap all this up in the componen?t The answer is flexibility. You will probably want to add a title and a page number or something we never could anticipate, and you can do all of this in the PrintPage event. The sample below shows how the printing mechanism is splitting the print to many pages over the Y-axis (grid rows). To split the print to several pages over the X-Axis (different pages show different time), you should execute the print operation two (or many) times with different values set on the datescaler. Like this: private void Print_Click(object sender, System.EventArgs e) { Question How come the images for zoom in zoom out does the reverse of what they should? + zooms out and - zooms in! Answer There are two common takes on this: + goes closer - goes further away. OR + shows more time and - shows less time... We have chosen the latter one. Right or wrong? Anyway you can switch the icons by implementing Gantt_ASP.OnGetResource Implement Gantt_ASP.OnGetResource and when id == "PlexityHide.GTP.WEB.zoomin.gif" etc. you can send in another image… Snap time item placements while moving Administrator — Thu, 22 May 2008 13:14:00 GMT Abstract: Question I know I can use DateScaler.Snap to control time item placement, but now I want to have the time item jump in discrete steps while the user moves it. Is that possible? Answer Sure, everything is possible: /// <summary> /// This is how you can quantify the movement, while moving, to, for example, 1 hour /// </summary> private void gantt1_OnTimeItem_Hoover_ForQuantifyTest(PlexityHide.GTP.Gantt aGantt, PlexityHide.GTP.TimeItemEventArgs e) { if (gantt1.MouseMoveKind==MouseMoveKind.move) { int orgpos=gantt1.DateScaler.TimeToPixel(e.TimeItem.Start+e.Diff); DateTime quantizedTime=gantt1.DateScaler.SnapTime(e.TimeItem.Start+e.Diff,new TimeSpan(1,0,0)); int newpos=gantt1.DateScaler.TimeToPixel(quantizedTime); int diff=newpos-orgpos; e.x =e.x+diff; } } Resizing the TimeItem''s Region Administrator — Thu, 22 May 2008 00:27:00 GMT Abstract: Question When the GanttRow.CollisionDetect and GanttRow.IncreaseRowHeightOnCollision properties are set to true, the TimeItems that are not in a collision-area are shown as filling the entire height of the now expanded row. When trying to resize them using the suggested solution in Q10210, the drawing itself shows a regular sized TimeItem, but the text and all the events still apply to the old Region, which covers the entire height of the row. How do I redefine the TimeItem's Region so that I will have a regular-sized and regular-behaving TimeItem while still enjoing the benefits of showing the collisions on an increased row? Answer This is how to use the OnTimeItem_UserDrawBounds and OnTimeItem_UserDraw together: In the OnTimeItem_UserDraw event change the given Rect and Bounding Region (make them as thin as you need) Start with the rect and create a new region: e.Rect=rect; e.BoundingRegion = new Region(rect); In the OnTimeItem_UserDrawBounds you must do the same(assign new e.Rect and e.BoundingRegion), since this event Is fired when the logic is finding out the size of the time item for other reasons than drawing. private void buttonSetUpTestSizeOverride_Click(object sender, EventArgs e) { gantt1.OnTimeItem_UserDraw += new TimeItemEvent(gantt1_OnTimeItem_UserDraw); gantt1.OnTimeItem_UserDrawBounds += new TimeItemEvent(gantt1_OnTimeItem_UserDrawBounds); GridNode gn=new GridNode(); gantt1.Grid.RootNodes.Insert(0,gn); GanttRow gr = GanttRow.FromGridNode(gn); TimeItem ti=gr.Layers[0].AddNewTimeItem(); Script manager is ambiguous in the namespace system.Web.UI Administrator — Thu, 15 May 2008 19:50:00 GMT Abstract: Question I went into vb.net5 and started a new web site and tied doing the instructions for To create an ajax enabled Gantt chart. The error is Script manager is ambiguous in the namespace system.Web.UI. After this I tried adding it to my current ajax aspx vb.net 2005 and got the same errors. And can't get the old versions in source safe. The error is Script manager is ambiguous in the namespace system.Web.UI. I think something got messed up in the .net framework or something. Don't know how to fix this. Answer My guess is that your web.config is messed up. Best solution? Create a new project drag an update panel to it (with the VS and ajax version you want). How can I choose which printer to use? Administrator — Wed, 14 May 2008 21:01:00 GMT Abstract: Question Using the print facilities of your object I can just launch the print preview based on the current default printer and its configurations (like paper size, etc). I wonder how can do to let the user to select which printer to use and to properly configure it before printing the gantt. Answer Stole this more or less from MSDN: public void Printing(string printer) { try Is it possible to have different font color for Header and the cell? Administrator — Tue, 25 Mar 2008 16:10:00 GMT Abstract: Question Hi, Is it possible to have different font color for Header and the cell. If I set property in the celllayout it applies to whole of grid. I want to apply different font colors to the headers and the cell. Answer Yes. You can assign a unique CellLayout to each cell. The Column heads can also be treated as cells: GridColumn.ColumnCell so you can assign CellLayouts to them to. You can find a CellLayout from a CellLayoutName like this Grid.CellLayouts.GetFromName("theNameOfTheCellLayout"); This sample shows how a header cell in Gantt_ASP is given a Bold type face: CellLayout cl=new CellLayout(); cl.Name="ABoldCellLayout"; cl.Font=new Font(FontFamily.GenericSerif,14,FontStyle.Bold); Gantt_ASP_Vendor.Gantt.Grid.CellLayouts.Add(cl); // When using Gantt_ASP it is even more important to add the cellLayout to this collection, or else it will not we added to the css Gantt_ASP_Vendor.Gantt.Grid.Columns[0].ColumnCell.Layout=Gantt_ASP_Vendor.Gantt.Grid.CellLayouts.GetFromName("ABoldCellLayout"); How do I use a CSS file with the GTP.NET? Administrator — Tue, 18 Mar 2008 22:57:00 GMT Abstract: Question How do I use a CSS file with the GTP.NET? Answer Normally you do not want to add a css of your own to change the styles of the grid since one is generated for you based on the settings of the CellLayouts. This way you can have almost the same view in WinForms and ASP.NET. The class names of the cells is taken from the names of the used CellLayout. You can choose to use an External style sheet or a style sheet section in the rendered page. This property comes into play: ExternalStyles, When setting ExternalStyles to true the css stylesheet is NOT embedded into the rendered html. Intstead you must add an attribute to the head section. You will also need to create the theganttstyles.css and you can do this by calling UpdateExternalStyles with the file name of your choice. If you leave ExternalStyles to false (default) you do not need this, but on the other hand ajax does not update the head section so under certain circumstances you can run into troubles using embedded styles. UpdateExternalStyles, When setting ExternalStyles to true the css stylesheet is NOT embedded into the rendered html. Typical scenario for when to create to the css file: Gantt_ASP_Main.ExternalStyles=true; // You have decided to use external styles, this might be set in the object inspector already LoadMainProjectData(); // You fill the Gantt with data AND you probably create some CellLayouts format grid cells if (!File.Exists(Page.MapPath("GanttStyle.css"))) // If you have no need for dynamic styles, the file does not need to be written every time... Gantt_ASP_Main.UpdateExternalStyles(Page.MapPath("GanttStyle.css")); // This call reads the CellLayouts and create the css content, and saves the file.

Lets say for a button if I want to add a mouse over event in vb.net we can add like this Button1.attributtes.add("mouseover","mouseover()") I tried use ClientSideJavaScript_TimeItemInit event. Is there any function avilable in plexityhide which i can add mouseover evenet for timeitem. Answer Sure, Go like this: Gantt_ASP.ClientSideJavaScript_TimeItemInit = "aImgElement.onmouseover=(function(event){alert('hello');});\r "; Is there a way to find if the time item is changing a row in the OnValueChangedGantTime event. Administrator — Sun, 02 Mar 2008 11:59:00 GMT Abstract: Question My question is - Is there a way to find if the time item is changing a row in the OnValueChangedGantTime event. The thing that I am doing cannot be done in or after the OnGantTimeChangeRow event. I tried using the theGant.RowList.FindRowFromY(lngY).TreeNode.GridRowIndex but it does not work for some cases. Answer Use the theGant.RowList.FindRowFromY(IphGantX3.MousePositionGantArea.Y) if the returned row is different than the row currently owning the time item (theDataEntity_GantTime.Row) this is a move... You can check this in the OnHintInfo event and put the information in a membervariable that you later read in the OnValueChangedGantTime event. Check the argument theDataEntity!=null, and also check Is there a way to change the style of selected items? Administrator — Wed, 27 Feb 2008 17:23:00 GMT Abstract: Question Is there a way to change the style of selected items? Answer The built in selection highlight is limited to the TimeItemLayout.SelectHandles=color, but if you want something more fancy it is really easy to implement the OnTimeItem_SelectionChanged event and simply change the TimeItemLayout if the time item is selected or de-selected. The event is called both for selection and de-selection, so that you can set the timeitemlayout back to the original. Just check the e.TimeItem.Selected, true=selected false=de-selected. Bigger jumps on datescaler scrolling Administrator — Thu, 31 Jan 2008 11:54:00 GMT Abstract: Question I would like to change the user scroll step. I want the user to take bigger steps in time when they press the datescaler scrollbuttons. How can I go about that? Answer One way to solve that is to implement the OnBeforeScaleOrSpanChange event and change the deault values. private void buttonSetUpBiggerJumpOnTimeScroll_Click(object sender, EventArgs e) { gantt1.DateScaler.OnBeforeScaleOrSpanChange += new BeforeScaleOrSpanChangeEventHandler(DateScaler_OnBeforeScaleOrSpanChange); } void DateScaler_OnBeforeScaleOrSpanChange(DateScaler dateScaler, BeforeScaleOrSpanChangeArgs e) { if (e.DateScalerChangeKind==DateScalerChangeKind.userpan) { TimeSpan defaultjumpsize=e.NewStartTime-gantt1.DateScaler.StartTime; // 4 times bigger jumps than default... e.NewStartTime = gantt1.DateScaler.StartTime + defaultjumpsize + defaultjumpsize + defaultjumpsize + defaultjumpsize; e.NewStopTime = gantt1.DateScaler.StopTime + defaultjumpsize + defaultjumpsize + defaultjumpsize + defaultjumpsize; } } I want to extend the grid columns so that they always fill the space in grid Administrator — Thu, 31 Jan 2008 11:25:00 GMT Abstract: Question How can I automatically extend the grid column to use up all the space in the grid? Answer Implement the Grid.Resize event and do something like this: void Grid_Resize(object sender, EventArgs e) { How do I set the DateScaler properties to display the current date as starting date. Administrator — Thu, 31 Jan 2008 11:11:00 GMT Abstract: Question How do I set the DateScaler properties to display the current date as starting date. I tried to set the StartTime and StopTime in the DateScaler properties box but the component is not refreshing, but it sets the StopTime to the date i specified, but the start time is always Aug 5 2003. Also I want the date should display in Hours... Answer It has come to our attention that setting the DateScaler.StartTime and DateScaler.StopTime only works if done in such a way that StartTime is always smaller than StopTime... This is considered a bug with low priority (exists in 1.3.1). The workaround is to use the DateScaler.TimeSpanSet(Start,Stop) that will work. Going like this... DateTime t = DateTime.Today; t.AddDays(1); gantt1.DateScaler.TimeSpanSet(DateTime.Today, t); ...will give you a view of one day. Depending on the width of the Gantt-area the scale will find a value that is the best presentation for one day. To get another resolution you add more days to the view. Another similair question was: I want to center the view around a specific time item: If you know where you want the middle of the visual span (xmiddle=timeItemStart+(timeItem.Duration()/2)) you can set the Datescaler to show this by calling Gantt.DateScaler.TimeSpanSet(xstart,xstop), where xstart=xmiddle-(timeItem.Duration()/2) and xstop= xmiddle+(timeItem.Duration()/2) Can the control drag the parent TimeItem to a different row and have all its associated sub items move with it? Administrator — Sun, 20 Jan 2008 18:36:00 GMT Abstract: Question Can the control drag the parent TimeItem to a different row and have all its associated sub items move with it? Answer There is no property to set to do this automatically; you will need to react to an event and move child time items according to your rules. In GTP.NET I would suggest to implement OnTimeItem_ChangeRow and in this event track down the child nodes by e.TimeItem.GanttRow.GridNode.SubNodes[0..x] and for each SubNode y do Gantt.GanttRowFromGridNode(y) then loop over the layers and timeItems and move them the way you need (or move the whole GridNode to a new parent if that is what you want). Calculated columns in a databound Grid Administrator — Tue, 01 Jan 2008 14:04:00 GMT Abstract: Question I am using the OnBeforeDSToCell event to format some data to be displayed in the grid. But I want one of my columns to be calculated based on two other columns - how can I do this? Answer Since the columns are filled from 0 to n, you cannot read the x+1 column when handling OnBeforeDSToCell for column x. But I suggest that you get your data from the datasource instead: void NodeDataConnect_OnBeforeDSToCell(NodeDataConnect aNodeDataConnect, CellAndDSArgs args) { if (args.Cell.Column.Index==theCellCalclulatedFromTwoOtherValues) args.Value=(args.CurrencyManagerListItem as DataRowView).Row["Col1"].ToString()+(args.CurrencyManagerListItem as DataRowView).Row["Col2"].ToString(); } Resize columns by automagic Administrator — Fri, 21 Dec 2007 13:53:00 GMT Abstract: Question I would like to have the columns in my grid autosize to encompass the longest value. How can I do this? For example if column 1 of row 1 has a value of 'IT' and column 1 of row 2 has a value of 'Accounting' then the size of column 1 should be wide enough to see all of the word 'Accounting' without the user having to increase the size manually every time. Thank you. Answer You will need to do this yourself by detecting values in the cells and meassure them, then change the width of the column. I would implement OnGridPaintBackground, not that I will draw anything, but this will be called when the data is in place and the screen must update. I would loop thru the nodes on screen (Grid.GridStructure.VisibleNodes) and loop thru each cell finding out the widest entry in each column (by meassuring the content using the Graphics object in the OnGridPaintBackground event arguments). Once I have this information I need to compare it with the current GridColumn widths. And if my "rules" says that the widths should change, change them. BUT it is important that you only change the widths if it is necessary, since the change will trigger a need for a new drawing pass (calling OnGridPaintBackground again). You can easily get into recursion if you change the display in an event that draws the display... But once you are aware of the risk it should be controllable. To catch changing values implement OnAfterEditCell, to set the When connected to a database: how can I change the color of different TimeItems individually? Administrator — Thu, 06 Dec 2007 08:05:00 GMT Abstract: Question When connected to a database: how can I change the color of different TimeItems individually (for instance: same resources the same color)? Answer Good question, how do you manage to set specific properties to data that is added automatically with databind. For time items you willl find a TimeItemDataConnect for each layer. It is the TimeItemDataConnect object that resolves the events in the datasource to actual time item property values. You can implement the TimeItemDataConnect.OnBeforeDSToTimeItem (the event is not available in the property grid but just type yourLayer.TimeItemDataConnect.OnBeforeDSToTimeItem+= and hit tab in VS) In this event you can inspect that data from the datarow and you can do additional things on your time item, like setting a TimeItemLayout etc. This event is also good for conversions, if your datarow has start and length instead of start and stop. New: Now there is an easier way to intercept what happens each time the TimeItem is updated from the datasource: OnEachListItemWhenDataBound_TimeItem In the sample below we use it to add TimeItemTexts: /// <summary> /// Our bookings are represented by TimeItems in the Schedule /// Here we extract further information on TimeItemTexts that we want to show /// </summary> private void gantt1_OnEachListItemWhenDataBound_TimeItem(object GTPComponent, EachListItemWhenDataBoundArgs e) { if ((e.GTPObject as TimeItem).TimeItemTexts.Count==0) { TimeItemText tit=new TimeItemText(); tit.Text = (string) (e.CurrencyManagerListItem as DataRo So far it looks great, but I have not been able to change the row height? Administrator — Tue, 27 Nov 2007 08:58:00 GMT Abstract: Question We are evaluating your phGantX component for use in visualizing info from a time & attendance app. So far it looks great, but I have not been able to change the row height. We need to make them taller since we need to draw a time bar and several markers underneath. However, using the SetRowHeightGrid does nothing, and the GetRowHeightGrid always return zero. Please advice. Answer Make sure you set IphGantX3.UseGrid=true, "Set this to true to use the grid instead of the tree. You must do this before adding any rows since all rows added are owned by the component (grid or tree) that is active when the row is created." If IphGantX3.UseGrid=false the comctrl treeview is used, and this cannot handle rowheights, columns etc The Grid is fully hierarcical and can do everything the old tree can. Print to a bitmap Administrator — Fri, 23 Nov 2007 09:29:00 GMT Abstract: Question I would like to enhance the print functionality for GTP. I’d like the productvery much , only the print functionality is a bit poor. My question is how to obtain the image that is been posed on the printpreview. When a print preview is genarated I can only find information about the graphics object but not the image: System.Void PrintPage ( System.Drawing.Graphics G, System.Drawing.Rectangle Margins, System.Int32 aGridWidth, System.Int32 aDateScalerHeight, System.Boolean& HasMorePages) I noticed that there are images(bitmaps) for the grid and datescalar but I'm looking for one image object of the complete gtp (grid + datescalar). Can you please give me some information for my problem? Answer You can send in a graphics object that comes from a bitmap like this: Bitmap b=new Bitmap(w,h); Graphics g=Graphics.FromImage(b); And the call PrintPage with that... You will then get the complete print in bitmap! Sample code: // Print to a bitmap file Bitmap bm=new Bitmap(CapTimingGantt.Gantt.Width, CapTimingGantt.Gantt.Height); Graphics g = Graphics.FromImage(bm); g.FillRectangle(new SolidBrush(Color.Tomato), r); g.DrawRectangle(Pens.Black, r); bool hasMorePages = false; Rectangle r = Rectangle.FromLTRB(0, 0, CapTimingGantt.Gantt.Width, CapTimingGantt.Gantt.Height); CapTimingGantt.Gantt.PrintInit(null); CapTimingGantt.Gantt.PrintPage(g, r, 150, 28, ref hasMorePages); CapTimingGantt.Gantt.PrintEnd(); bm.Save("c:\\temp\\test2.bmp"); To print to an EMF instead go like this: `// P` XP visual styles Administrator — Sat, 17 Nov 2007 20:55:00 GMT Abstract: Question What does one need to do to enable XP visual styles in the Scrollbars in the Grid in GTP.NET?

Administrator — Sat, 17 Nov 2007 18:18:00 GMT Abstract: Question The Datescaler is showing Month-->Date resloution.in two steps. But I want to make it into 3 Steps, i.e. Month-->Week--->Date resloution Answer Currently the DateScaler does not have built in support for a three band presentation. The somewhat complex workaround is to implement OnDateScalerPaintForeground and erase the default content and draw all three bands yourself. If you choose to go down this path you will want to use the TimeToPixel method and simply iterate from start to stop in your choosen resolution, call TimeToPixel for each step and draw a mark and a text. We have offered the three band datescaler as a user-paid-for-extension to some clients but we have no deal yet. The n-band datescaler is on our todo list but not prioritised yet (and this means that we have no idea when we will implement it). I am trying to add 2 texts to a time item.

Administrator — Sat, 17 Nov 2007 12:25:00 GMT Abstract: Question I am trying to add 2 texts to a time item. I want to be able to show text1 on one line and text3 on the line below text1. I have tried the code below but only the last text gets displayed. How can I accomplish this? Answer To accomplish this use two TimeItemTextLayouts with different padding. The second one should have a top padding to make it appear under the first one: TimeItemText titxt = new TimeItemText(); titxt.Text = "Test"; titxt.TimeItemTextLayout = gantt1.TimeItemTextLayouts.GetFromName("Default"); titxt.TimeItemTextLayout.Color = Color.Black; titxt.TimeItemTextLayout.Font = new Font(FontFamily.GenericMonospace, 10, FontStyle.Regular); titxt.TimeItemTextLayout.VertAlign = StringAlignment.Near; ti.TimeItemTexts.Add(titxt); Ti Multiselect in the TimeItemArea Administrator — Sat, 17 Nov 2007 11:35:00 GMT Abstract: Question I know you can multiselect time items by holding the ctrl key while clicking them, and that you can get to all selected time items by the method gantt1.GetSelectedTimeItems(). But what if I do not allow multi select? How can I stop it? Answer To effectively stop multiselect for the TimeItems go like this: gantt1.OnTimeItem_SelectionChanged += new TimeItemEvent(gantt1_OnTimeItem_SelectionChanged); I set the size of gantt_asp to 100% but the grid is resizing instead of the gantt chart area. Is there a way the Gant_ASP's gantt chart area will resize by browser's window size? Answer Currently we do not a built in capability to adjust from client side size changes. If you need it you will need to trigger a postback from the resize and supply the new sizes and adjust the size of the Gantt_ASP server side. How to get the snapped time values in the Gantt1_OnTimeItem_StopValueResize event? Administrator — Wed, 31 Oct 2007 12:02:00 GMT Abstract: Question I have a gantt chart/grid where I have set the start and stopsnap times. After I change the stop time of timeitem, the cooresponding column in the grid changes to the 'snapped' time. How can I get this value to use instead of the true time from the Gantt1_OnTimeItem_StopValueResize event? Trying: e.TimeItem.GanttRow.GridNode.GetCell(3).Content.Value gives me the original stoptime of the timeitem and : Gantt1.FocusedTimeItem.Stop.Add(e.Diff).ToString gives me the new stoptime w/out being snapped as indicated. Thank you for your help. Answer The snapping is calculated after the OnTimeItem_StopValueResize event, but you can use the same logic we do to calculate the snapped value: Gantt.DateScaler.SnapTime(time,precision). So try this: TimeBeforeSnap=e.TimeItem.Stop.Add(e.Diff); TimeAfterSnap=Gantt1.DateScaler.SnapTime(TimeBeforeSnap,e.TimeItem.TimeItemLayout.SnapStopTime); I want to keep the original Height of Some time items...

Answer You can set IphGantRow3.CollisionDetectBetweenLayers=false and keep some activities in one layer and the others in another layer. The data in the bound datasource must be mangled before presentation. How? Administrator — Sat, 20 Oct 2007 12:44:00 GMT Abstract: Question Because of the data in my normalized tables, when I use a databound gantt, no column in my DataTable has the data I would like to display in my GTP.NET grid. I figured that I could use OnGridCustomCellDraw and OnGridPaintForeground to paint the cell much in the same way that I use the UserDraw, can I use these methods to draw the text in my Grid? The problem I'm having is that the OnGridPaintForeground is the only event two that ever gets called, and based on the arguments given and the frequency it is called, I don't think it is the appropriate for drawing the text for the grid column. I must be missing some property that I need to set - similar to what you do with the TimeItemStyle when you are using UserDraw on TimeItems. Are there any examples available where this is done? Answer One way is to produce a complex datasource that takes in the values from your other tables, but I think what you really want is a way to intercept what is put on the screen and also (if editable) a way to intercept what is put in the datarow when the grid is edited... For this you need Grid.GridStructure.RootNodes.NodeDataConnect There is currently no sample on this but the logic is the same as for time items (TimeItemDataConnect) and there are some samples for that... Look at this article : http://plexityhide.dyndns.org/InstantKB13/article.aspx?id=10098 What you want to do is to implement the events: Grid.GridStructure.RootNodes.NodeDataConnect.OnBeforeCellToDS AND Grid.GridStructure.RootNodes.NodeDataConnect.OnBeforeDSToCell Once there you can do whatever you need with the data and fill the cells...

What you need to do is to, depending on your design criterias, is to cache the dataset you use and restore it for postback events. This is shown in the LetsBuild_ samples series available here http://www.plexityhide.nu/ajaxdemo/LetsBuild_ProjectPlanner.aspx In short this is done like this: protected void Page_Load(object sender, EventArgs e) { ... if (Page.Session["loaded_proj"] == null \|\| (bool)(Page.Session["loaded_proj"]) == false) { // OK, New user connect to your DB and fetch the data... f1.dataSet1.ReadXml(Page.MapPath(".\\App_Data\\project.xml")); System.IO.MemoryS OnTimeItem_AfterMove event, the TimeItemEventArgs returns 0 in its X and Y fields?

When trying to implement this by using the OnTimeItem_AfterMove event, the TimeItemEventArgs returns 0 in its X and Y fields. This is not good, since I am trying to find the "lower" timeitem by using the Gantt.TimeItemFromPoint method. 1) Why does the TimeItemEventArgs return these values? 2) If this is not fixable, how do I find the relevant timeitem? Answer 1) The mouse position is not relevant after the mouse button is released, and the draw rectangle of the time item is not updated until the next render-sweep, what is valid here is the Start and Stop of the time item (collisiondetection may affect Y pixel pos, datescaler changes my change X pixel pos) Ajax samples source code Administrator — Tue, 16 Oct 2007 22:37:00 GMT Abstract: Question Hello I see that you have an Ajax web example in http://www.plexityhide.nu/ajaxdemo/Default.aspx, can I download the source code for this example? or can I download any similar example in GTP.NET 3.0 in web?

Is there a way to show more than one header-line (more than one column) and / or mantain the Cell layout in the header? Thank you. Answer You can change the header cell layout by setting the GridColumn.ColumnCell.CellLayout to the CellLayout of your choice. The header cells use the HeaderBackgroundColor, HeaderBackgroundGradiantColor properties for colors, besides that they work the same way.
