I am using Visual Studio 2008, SQL Server 2008 Reporting Servces, WSS 3.0. Reporting Services is configured in SharePoint Integration mode. I am displaying reports on SharePoint pages using the Report Viewer Web Part.
Reports are deployed all in one folder (document library). Top level reports display just fine. When I go to sub report usually by going to he next page (unless the first report is a multiple page report), I get the "Subreport could not be shown" error.
I understand that this error comes up if there are any errors like no parameters passed, or sme other issue with the sub report. All of these errors can be repeated and fixed at design time in VS 2008. I even have VS 2008 installed on the same box that is running SRS 2008 and WSS with the same database.
I get the error only when the report runs in the report viewer web part. If I go to VS 2008 and run the same report and subreport on the same server I get no errors.
Can any one help?
