The above code works fine.I have added an Update Panel in the page to avoid post back, But when i add the button click as a trigger
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnSubmit" />
</Triggers>
in the update panel to avoid post back, i get the following error.This happens when i add the button click as a Trigger to the update panel.
