How do you reset a grid's ViewDefinition back to the default table view? Setting it to nothing does appear to work.

Is it possible to format the selections in a GridViewComboBoxColumn so that different selections have different background colors, or other attributes for that matter?
For example,
1) Red - Red background
2) Green - Green background
3) Yellow - Yellow background
Thanks,
Ken...

Hi,
Is there a way to get either the bounds or the client x,y position of a RadTreeNode item so I can point a Tooltip at a tree item? Either that or be able to get the window handle for the tree item so I can use that in the tooltip.Show() method.
Thanks
Paul

Hi,
I would like to have a textbox control (or maskededit) which mimic GridViewDecimalColumn default editor. That is a control that accepts only decimal numbers, that could have a minvalue and a maxvalue, that do not has the need for a mask. Exactly as the GridViewDecimalColumn editor.
thank you
Andrea

Hello,
I'm trying to set the grid width of the child table but cannot find the property/method to do so?
I've set the outer grid width fine I think.
and then try to set the inner (child) grid on the on gridview formatting event:-
Attached is the screen print of the output and what I'm trying to achieve for clarity.
Many thanks
Terry
