That's what the error message 'System.ArgumentOutOfRangeException' would have me believe as well, but I'm not searching for a value before the query and everything present in the database ends up in the combobox.

The other error message 'System.Data.EvaluateException' occurred in System.Data.dll when the form closes is equally baffling.

If i comment out the combobox fill both error messages no longer appear, so that's definitely where its occurring. I'll try some other stuff to see if i can shake something loose. Thanks for everyone's responses.
