How to get FileUpload to trigger UpdateProgress/ProgressTemplate
Posted on 2009-02-17
I have a FileUpload control that is on an AJAX ASP.NET page. It is within the UpdatePanel. In my UpdatePanel I am using the UpdateProgress to display an animated gif that asks the user to please wait.
When I click 'Upload' how do I trigger the UpdateProgress section to work?
Alternatively is there an easier way to (1) either tell the user to please wait or (2) show a progress bar during the upload?
Full working examples with ASPX/AJAX page and code are preferred if possible...
