If you are using Update Panel on your webpage then File Upload Control will not work with Asynchronize Postback. so you need to set Postback trigger on the button click.
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<Triggers>
<asp:PostBackTrigger ControlID="btnSubmit" />
</Triggers>
</asp:UpdatePanel>
</Triggers>
</asp:UpdatePanel>
