Hi Niraj,

My report is drill down report. This error comes at the rs.Render(........) method of the reporting web service.

Thanks.

Gunjan.

Hi Gunjan,

Well..."http://gshah755/ReportServer/ReportService.asmx"....did you try using "localhost" in-place of gshah755 [which I guess is your system..:)]..Just try adding Web Reference for "http://localhost/reportserver/reportservice2005.asmx".....in your application..

I hope...it will work....

Regds,

Niraj
