Can I populate a Dropdown list in a GridView from another Dropdown list

I have a Gridview control that contains 2 DDLs. The first one is populated on page load (from a Generic list in the code behind) and is working with no problems. I want to populate the 2nd DDL by making a selection in the first DDL which in turn would call a DB method and cause a postback.
I've tried using the "OnSelectedIndexChanged" method for the DDL and the "FindControl" method for the 2nd DDL, but the GridView can't find it on Postback and throws an error. I've also tried using the "onSelectedIndexChanged" method for the GridView bu...
