Hi schrecengost,
I found a solution for me.
I deinstalled Infragistics, Ajax Extensions and IIS-Server. Then I installed again IIS, Ajax-Extensions and Infragistics and now it works.
Perhaps you can try first to register ASP.NET again in IIS with the following command
aspnet_regiis -i
I had to do this after the new Installation of IIS. You can try this before the Deinstallation.
Best wishes.

HI,
I have exactly the same problem.I deinstalled Infragistics 2008.3 and install Infragistics 2010.3 on my machine.Now, when i call a web site with the control WebDataGrid i get the error
Die Datei oder Assembly "Infragistics2.WebUI.UltraWebGrid.v8.3, Version=8.3.20083.1009, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb" oder eine Abhängigkeit davon wurde nicht gefunden. Das System kann die angegebene Datei nicht finden.
I have no reference to this old control.When I call the web site from Visual Studio with the integrated Cassini Server everything is ok.I only have the error with my IIS.
I hope someone can help.
Thanks
