I am validating my control on my CS page.

if (FileUpload1.HasFile)

but this if condition is returning always false. I am not getting what is the actual reason! Can anyone help me in this?

I have put my FileUpload Control into a Updatepanel. Then apply a trigger on those buttons from where data is submitting.

 <td>
      <asp:UpdatePanel runat="server" ID="updatepanel1">
          <Triggers><asp:PostBackTrigger ControlID="btnsubNxtClm" /></Triggers>
          <Triggers><asp:PostBackTrigger ControlID="btnsubmit" /></Triggers>
          <ContentTemplate>
          <asp:FileUpload ID="FileUpload1" runat="server" />
          </ContentTemplate>
      </asp:UpdatePanel>
</td>

FileUpload control is not compatible with UpdatePanel. You have two options

  1. Move the control outside of UpdatePanel
  2. If not possible, add a PostBackTrigger on the UpdatePanel

An example

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