Unable to Call SSRS 2008 R2 Report from C#.NET (Visual Studio 2010)

Hi,

I have SSRS REport developed  in 2008 R2 and placed into the Report Server details mentioned below:

variables declared in Web.Config file

<add key="reportingServer" value="http://bdow8vadsql1/ReportServer_BDOW8VADSQL11" />
<add key="reportFolder" value="/SERIPSCReports/Reports" />

I m able to call the report directly from Report Server and is getting open. The issue is if i call the report from C#.NET am getting following error:

• The operation you are attempting on item '/SERIPSCReports/Reports' is not allowed for this item type. (rsWrongItemType)

Please help to resolve it.

Regards,

Raj
