Has anyone else seen this behavior?
Running Visual Studio 2010 Ultimate with Infragistics NetAdvantage 10.1 controls on Windows 7 Ultimate and after I added a WebDataGrid to my page, in design mode it says "Requesting Data..." in the bottom left of the VS2010 IDE. Won't go away ... and won't allow me to add any more Infragistics controls in Design View or Source View.
Not sure if it is specific to WebDataGrid. I also have WebSplitter, WebTab, and WebExplorer controls on the page.
Doesn't do this on an empty Web Form. See image below (blue circle cursor is also running when this happens).
