Hi,

I tried to "resolve" a well known problem with AJAX UpdatePanel and <asp:FileUpload> by setting <asp:PostbackTrigger> for FileUpload control.

This file upload is situated in DetailsView control.

But when I try to compile my page and view it in browser I get an error
message:

A control with ID 'FileUpload1' could not be found for the trigger in UpdatePanel 'UpdatePanel1'.

But I know well that this control exists on the page as you can see
here

What I'm doing wrong?

Thanks for advice.
