Did anyone of you ever find a way of getting the Microsoft Report Viewer Control (Web) to work from within an Ajax UpdatePanel?
The only way really is to create an iframe with the report in there iirc. However, this post here a guy claims he has a way to fix it with some code. albeit i havnt even tried this as I have never had a need to show any of my reports in an update panel. I tend to keep my reports external of any ajax apps, for example when a report is requested i will open a new window with just the report. My users like that better anyhow.
