Thank you for your answer, it helped :) (And I also found a mistake in my steps :sigh: )

Hi I am facing same problem. I used reportviewer on user control and script manager is placed on master page, then in this case the report is not showing. I tried to user scriptmanagerproxy on my user control but not able to used it in proper way because of lack of knowledge on scriptmanagerproxy. Can anyone give me a small code demo? Thanks
