To my knowledge, you can't do this directly with the file upload controls in ASP.NET, specifically because the information is in the same thread. This is due to the HTTP POST of your file being in the same thread handling the update of the progress bar. You'll need to split the operations in some fashion, either using AJAX, Flash, or something similar.
