I upgraded from VS2008 to VS2010 and none of my reports work!
First, I had to replace all the existing ReportViewer controls with new ones. Then, when the page finally runs, it is stuck in a loop: I see the "Loading..." word and icon while the ReportViewer is loading, then a quick flash, and the page loads again!
What's going on? What am I missing that should obviously be changed to make these ReportViewers work? These reports were designed in VS2005/2008, and have been in production for several years.
Please help - I have a screaming client... (I know, we all do...)
