Hi everyone! I'am using Visual Studio 2010 with Telerik winform Q3 controls. I find one issue. Lets create simple winform application. Add to it radgridview control. In Properties window add some columns, add one template and add some columns for template. Create relation for master and child template in radgridview. Open "Document Outline" window (View->Other Windows->Dicument Outline). This window shows hierarchical structure of the winform. You can see that template is under the gridview. Now edit grdview properties with "Open property Builder". Do some changes and click OK. Now if you look to "Document Outline" window you will see that template is disappeared. Relation between gridview master template and child template is deleted. Why is it so? Is it bug?

Thanks.
Armen.

Problem with Filtering in Virtual mode (Q2/2010)

I think filtering in virtual mode in Q2/2010 is not functional. The same functionality in Q1 is ok. When filter is active (user enter some filter), I don't recieve CellValueNeeded events. When I try to set RowCount in FilterChanged event, I get exception "Object reference not set to an instance of an object."

[Solved] ContextMenu Item Image

Hi all,
I'm experimenting some troubles in setting an image for the menu item of a RadContextMenu. Via code no problem: I can add a RadMenuItem to a RadContextMenu, and I can set the Image property of the RadMenuItem. The question is: how to achieve the same result via designer? The items of a RadContextMenu have RadItem as static type, and thus the Image property is not available.

Thanks in advance for any help!
Best Regards
Roberto

GridViewTextboxColumn int value

I'm trying to make a GridView column usable for int properties.

I have actually a property defined as an "int". When I binded my DataSource to the GridView component, the column linked to the "int" field has been created as a GridViewDecimalColumn.

But, when I try to edit the column field, I have an exception saying: Object of type "System.Decimal" cannot be converted to type "System.Int32"

Did I missed something?

Thanks,

GridView
