Hello,

Before to buy Telerik Reporting i try to make a report programmatically with the trial version.

My first problem was in Silverlight you must quote this ligne :

WebRequest.RegisterPrefix("http://", WebRequestCreator.ClientHttp);

Else you have a message like below :
"Report is unavailable or session has expired."

My second problem unsolve is when I build my report programmatically I have got a NullReference Exception in the report Viewver.
I dont understand this Exception, but it throw only when I build the details.

Anyone has got an idea what is wrong in my source code?

My report :

public class MedialogSimpleTableReport : Telerik.Reporting.Report

{
