Prevent modification based on certain criteria (aka SelectedValueChanging)

[Francois]

Hi,

I would like to be able to prevent the user to change the value on certain situations but I cannot find an event that would help me do that.

I've found the MultiColumnComboBoxElement.TextChanging event, but that only works when the modification is made with the keyboard. I would need to be able to handle also the modifications made by the mouse, including the mouse wheel.

Any ideas?

Thanks!

Hello Francois,

Thank you for writing.

I would suggest using the CellValidating event of the EditorControl for your scenario:

radMultiColumnComboBox1.EditorControl.CellValidating += new Telerik.WinControls.UI.CellValidatingEventHandler(EditorControl_CellValidating);

Please give it a try and let me know if ti works for you.
 
Best wishes,
