Although I have found several posts about similar issues, I have been unsuccessful at getting this to work. I have two columns in a radgrid, one with a radcombobox. When choosing a value from the radcombobox in edit mode, I need to update client side the value of column 2 in the grid from a value in my radcombobox. I don't know how to get a hold of that column's edit mode textbox client side from the OnClientSelectedIndexChanged event of the radcombobox. Thanks
