asp:FileUpload control is not working in update panel in ascx control. Why? any work around.

<span dir="ltr">
    <asp:FileUpload ID="InputFile" runat="server" class="ms-fileinput" size="35" /> 
</span>

and also I added

<Triggers>
    <asp:PostBackTrigger ControlID="btnOK" />
</Triggers>

Still it is not working.
