Hey, how can I skip the ViewCellFormatting event while the grid is getting new data?

Maybe there's some property I can check before continuing formatting? I have two interdependent grids and would like to "pause" this event whenever any of them is reloading...

I use telerik UI for WinForms project(not WPF) How to prevent auto close of RadContextMenu when user clicks on item on it? Now, after mouse click on any item, it closes. In WinForms there is ContextMenuStrip.AutoClose property to prevent autoclosing. Is there analogue of the property on Telerik RadContextMenu?

Thanks

I drew an example in the picture.
The format of the data table read from db is shown on the left.
I want to show this on the grid and zoom in
Grouping does not show column information in the row that is being expanded/reduced, but I need information in all rows.
I want to express it like BOM.
I want to expand/reduce to a specific key flexibly according to the column of the table I'm reading, but I don't know what to do.

Hi,

I am trying to create a PDF Table but I  am missing one or more libraries that I should reference. The code fragment I am trying is as follows:

Table table = new Table(); TableRow firstRow = table.Rows.AddTableRow(); TableCell firstCell = firstRow.Cells.AddTableCell(); 

Block block = firstCell.Blocks.AddBlock(); 
block.InsertText("Testing"); 

Thanks

Hello,  I am adding a 15mb image to the background of a RadDiagramShape.  The problem I am running into is the RadDiagram eats up 1gb of memory every time I open the form.  Eventually if I don't call GC.Collect the Image.FromStream blows up due to a memory limit.  I have traced it back to the RadDiagram utilizing a ton of memory.  The question I have is what performance considerations should I be looking at with the control?  I included the steps I am taking to add in the image.  

Thanks in advance!
Brian

 

                uiMap.DiagramElement.IsBackgroundSurfaceVisible = false;
                uiMap.SelectionMode = Telerik.Windows.Diagrams.Core.SelectionMode.None;

                RadDiagramShape backgroundImage = new RadDiagramShape()
                {
                    Name = "Image"
                };


                backgroundImage.IsConnectorsManipulationEnabled = false;
                backgroundImage.IsRotationEnabled = false;
                backgroundImage.IsResizingEnabled = false;
                backgroundImage.IsDraggingEnabled = false;
                backgroundImage.CaptureOnMouseDown = false;
                backgroundImage.IsEnabled = false;
                backgroundImage.IsFocusable = false;
                backgroundImage.IsHitTestVisible = false;
                backgroundImage.ShouldHandleMouseInput = false;
                backgroundImage.Shape = new Telerik.WinControls.RoundRectShape(0);
                backgroundImage.DiagramShapeElement.Image = floorplan;
                backgroundImage.Width = floorplan.Width;
                backgroundImage.Height = floorplan.Height;
                backgroundImage.ShouldHandleMouseInput = false;
                backgroundImage.NotifyParentOnMouseInput = false;
                backgroundImage.CaptureOnMouseDown = false;

               uiMap.AddShape(backgroundImage);

                Telerik.Windows.Diagrams.Core.ToolService toolService = uiMap.ServiceLocator.GetService<Telerik.Windows.Diagrams.Core.IToolService>() as Telerik.Windows.Diagrams.Core.ToolService;

                if (toolService != null)
                    toolService.ToolList[0] = new CustomPanningTool();

                uiMap.ActiveTool = Telerik.Windows.Diagrams.Core.MouseTool.PanTool;

How to do this (I hope) simple action?

I tried to set BeginEditMode to different options, AllowEditRow is set to true, but when I press F2 (for example) nothing happens.

Data displayed ok.

What additionally have I do?

Why there is no guide in documentation? Or I didn't find it?

Thank you!
