Set a value to a combobox in a gridControl

Hi, I fill a dropdown list in a gridControl by a dataTable. My display member is number + description. So when the user select the item in the dropdown list I only want to the number. How I can use my dataTable for that ??

thanks !!

So, you want your DropDown to display something other than the DisplayMember. Is this correct?

I would probably try adding an Expression column to your datatable, and set teh expression ot concatentate the ValueMember and DisplayMember into teh string you want to see in the droplist. Then when you set the style.DisplayMember, set it to this Expression column.

Not exactly, so for exemple in my drop list I see : 99999 - General Departement, and when the user select an item I see only 99999. My value member is the ID of the description in the database. In fact I want to modify the display member of my drop list after a current cell changed !!!

I wish that with my exemple is more easy to understand !!!
Thanks a lot.
