is this AJAX? If so, you will not be able to update controls on the client
side using server side script in this manner.

Thanks Gregory.

Add a JavaScript routine to the button after it is clicked and then enable
it again after upload is completed.

One good product for upload, that handles a lot of this plumbing is
