Actually it can be done, as long as you use triggers, something like this:

<asp:UpdatePanel ID="UpdatePanel1" runat="server" ChildrenAsTriggers="true" >
<ContentTemplate>
<asp:FileUpload ID="FileUpload1" runat="server" />
<asp:Button ID="btnPostBack" runat="server" Text="My PostBack Button" OnClick="btnPostBack_Click" />
</ContentTemplate>
<Triggers>
<asp:PostBackTrigger ControlID="btnPostBack" />
</Triggers>
</asp:UpdatePanel>

Don't forget to include the enctype="multipart/form-data" in your <form> tag.

Hi
Good post!
But when i used your mthod it doesnt work for me. The Fileupload.Hasfile return false. but when i keep it outside the updatepanel no drama even with not including the enctype.
Any ideas

Mmm I forgot to mention that the updatePanel shown in my code, is a sub-UpdatePanel, that is, there should be another outer UpdatePanel around all your other code... hope this helps!

Just to say thanks to murking - your solution of a nested update panel and triggers worked great for me.
Thanks
