I tried to reply yesterday, but the reply could not be posted due to network issues... so here goes again.
I think that setting the selected value within the control's databound event may not be a good place. Instead, try to do it in the Parent control's (a FormView in this case) databound event. I haven't had a chance to try a sample, but this is one possibility that comes to mind. If you post a complete sample (at http://dotnetdevelopment.pastebin.com, for instance), maybe we can test and determine the exact cause of the problem.
