When trying to set the image for the GridRowHeaderCellElement, nothing appears. I have an old theme where this image shows up just fine.

I have attached a comparison. My old theme (right) and my new theme (left). My old theme was built from scratch a while back. My new theme was based on the "Visual Studio 2012 Light" theme. We gutted the RadGridView to start fresh.

We are trying to set the image to be used as the "selected row indicator" when the row "IsCurrent".

I have tried to embed several images into this element without any success.

Am I doing something wrong or not complete with the theme?

Dynamicly Adding to ContextMenu

I am unable to figure out how to add to the ContextMenu of a RadMultiColmnComboBox or a RadDropDownList. If I instantiate their ContextMenu property, it is only displayed when clicking the very edge of the control, which tells me there is a child or editor control laying ontop. But when I try to modify the EditorControl's ContextMenu through the ContextMenuOpening event, the event never fires.

radMultiColumnComboBox.EditorControl.ContextMenuOpening += (sender, args) =>

{

Console.WriteLine("ContextMenuOpening event");

};

This never fires.

first row/cell selection

Hello

I am facing a problem with radgridview, when i set propery of grid as:

radGridViewVeh.MasterGridViewTemplate.ShowColumnHeaders = false;

the very first row of grid appears as selected (by default). But when i select another row/cell and try to select the first row/cell again, it does not appear as selected. Logically, it should get selected and appear as dark blue(depending upon the theme) like for all other rows/cells. The problem is with first row/cell only.

Please suggest a solution asap.

I was not able to submit my support ticket as there was some problem in your server.

DrillDown Help

Hi,

I'm trying to get a Drilldown working on WinForms with VB. I've customised it as needed, however I'm getting an error when trying to DrillDown as below:

Unable to cash object of type 'System.Data.DataRowView' to type "TestApp.DrillDownDataInfo'

I've looked at the guide here - http://docs.telerik.com/devtools/winforms/chartview/features/drill-down

However I do not seem to have a access to the sample files:

SamplesCS.ChartView.Features.DJIAD.csv

SamplesCS.ChartView.Features.DJIAM.csv

SamplesCS.ChartView.Features.DJIA.csv

So I haven't been able to look at it properly. Any help on this would be much appreciated or even a working demo in VB?

Thanks in advance.

Delete key

Hi,

I would like to use a RadGridView and be able to tell when the user pressed the delete key. It's important that the grid does NOT actually delete the current row, but it seems like disabling this causes the KeyDown event not to fire when the delete key was pressed. Is this an intended behaviour? Please advise,

Thanks,
Gabor

DragDrop Between RadPageViews

Hi

Is it possible to drag and drop pages between two or more RadPageView controls? I used a RadSplitContainer to put two RadPageViews side by side, but can't seem to drag the pages between both of them.

Thanks.
