Cannot Create Objects from String Representations for the Report Property

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 website 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.
