Cannot Create Objects from String Representations

Environment

Product	Progress® Telerik® Reporting
Version	Q2 2012 and later
Report Viewers	WinForms, WPF, ASP.NET

Description

Cannot create an object of type "Telerik.Reporting.Report" from its string representation "MyNameSpace.MyClass, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" for the "Report" property.

Cause

This error might occur if you are using a WebSite project and you have the report class in the WebSite directly.

Solution

The issue is due to the fact that when using a WebSite, after rebuild, the following will always be different and it will not match with the originally assigned report: App_Code.__unch8s_n__. It is recommended that you follow the best practices and have the report in a separate class library that is referenced in the application or WebSite.
