Unable to get ASP.Net UpdateProgress to display

I have also the same problem with the UpdateProgressPanel. I found out that when you have placed an UpdateProgressPanel and associated it to an UpdatePanel, any postback from that UpdatePanel will cause the UpdateProgressPanel to show.

Another trick to do is to remove the AssociatedUpdatePanel parameter if you have a single UpdatePanel on the page, this will cause the UpdateProgressPanel to show every Async PostBack that happens.

UpdateProgressPanel can be placed anywhere in the code, except those areas that have predefined tags on it. It can be placed inside or outside the UpdatePanel and it will show if you have properly placed its CSS, Associated it to an UpdatePanel or just place it there and it will show up if an async postback result happens.

Don't put the update progress control inside the update panel control

Make sure the UpdateProgress 'DisplayAfter' is set up to 1000 (1 sec)
