i'm migrating an ASP.NET web application from .NET 2 to .NET 4.0 and have a problem about the reporting side.
The thing is whenever i try to call a report (via webservice reportServer), i have this exception : The Report Viewer Web Control requires a System.Web.UI.ScriptManager on the web form
From what i understood of this Exception is that i had to add scriptManager tag in the .aspx , which i did. The exception currently doesnt occur, but the report is now completly blank.
Do you guys have experienced the same thing and had anyone figure it out ?
Thank you
