    Hi Arun,

    I moved your post to CR for VS forums.

    Not sure what you are doing but I will assume you are writing a WEB app?

    I'll also assume your CR code is in the Page_Load section as well.

    Back around SP 10 there were some Standards changes we did and all of the CR code should be moved to the Page_Init section now.

    Did you remove all of the CR References and add them back in as well as the WEB Viewer?

    All assemblies should be 13.0.03500 now.

    You also need to use Sessions and PostBack to keep the report in scope.

    Don
