fileupload fails in updatepanel

[Jeremy]

I have a fileupload component and a submit button inside an updatepanel.
(C#, asp2). In the debugger in page load, I see that the hasfile property
is false, even though the fileupload control was used to select an existing
file on the client.

If I move the 2 controls outside the updatepanel then hasfile is true in
page load.

How to workaround this?

Following up .. On the asp.net ajax site, in the overview page,

http://www.asp.net/ajax/documentation/live/overview/UpdatePanelOverview.aspx

I find the following

"To use a FileUpload control inside an UpdatePanel control, set the postback
control that submits the file to be a PostBackTrigger control for the
panel."

However, this does not work. IOW, adding the submit button's onclick event
as a trigger does not change anything.

Jeremy,

The UpdatePanel control is incompatible with the FileUpload control.
Period.

I have a simple control at http://pjondevelopment.50webs.com/articles/asyncupload.html
that people are using to circunvent this problem.

Take a look.
