[Mehmet]

Hi Telerik,

I couldn't filter between the two combobox on the RadGridView.
I want to;
when is selected item in first combobox,
second combobox must be filter, according to the first combobox selected item.

This filter must be run insert and update mode.

How can I do?

 

Thanks,
Mehmet
