Hi,

is this a WinForms application?
is the ComboBox using data binding?
which event are you using, and what's inside its handler (please show relevant code).
have you looked at the actual SQL command when it works and when it fails?
are you using try/catch blocks which do actually catch and show exceptions?
did you single-step with the debugger?

and/or possibly read ComboBox SelectedItem, SelectedValue, SelectedWhat??? – jaredpar's WebLog[^]

Smile | :)
