Hi Imran Khalid,
Thanks for your question.
We have not developed a reporting tool for Silverlight, yet. There are certain limitations we cannot overcome for the time being. However, we prepared a special demo that shows how you can integrate our Telerik Reporting tool and RadTabControl for Silverlight You can find the demo and the source code at:
Telerik Reporting in a Silverlight3 application
Hope this helps.
Sincerely yours,
Nick
the Telerik team
