How to disabled Raddropdownlist

$

Hi!  

    I have a radDropdownlist element inside a radGrid, I have to decide to enable/disable the radDropdownlist element base on it's selected value.  I have

searched and tried the solutions from the forums.  There are suggestions to place code in page_PreRender, ItemDataBound or ItemCreated events and check

e.item as GridDataItem or GridPagerItem and then findControl, but it could never find my dropdownlist control.

Any suggestions? What event should trigger the checking?

Thanks in advance!

Sharon
