I have solution for file upload control in update panel as follows

XML

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
          <Triggers>
              <asp:PostBackTrigger ControlID="Button5" />
          </Triggers>
          <ContentTemplate>
              <asp:FileUpload ID="FileUpload2" runat="server" /><br />
              <asp:Button ID="Button5" runat="server" Text="Button" OnClick="Button5_Click" />
          </ContentTemplate>
      </asp:UpdatePanel>

But it will give the result as HTTP Error 400 - Bad Request.

Hi madhu, you must have something going on your page apart of the code you mentioned over here. I gave the code a real try and it works without any hassle. I suggest you to check the rest of your code again.
Happy Coding :)
