Report Viewer Configuration Error

Question

I want to display report inside of SharePoint. My ASPX page contains one Microsoft.ReportViewer.WebForms.ReportViewer control. When I try to open this page, I get error:

Report Viewer Configuration Error

The Report Viewer Web Control HTTP Handler has not been registered in the application's web.config file. Add <add verb="&ast;" path="Reserved.ReportViewerWebControl.axd" type = "Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> to the system.web/httpHandlers section of the web.config file, or add <add name="ReportViewerWebControlHandler" preCondition="integratedMode" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> to the system.webServer/handlers section for Internet Information Services 7 or later.

The attempt to connect to the report server failed. Check your connection information and that the report server is a compatible version.

Client found response content type of 'text/html; charset=utf-8', but expected 'text/xml'. The request failed with the error message: -- 401 UNAUTHORIZED<RSError xmlns="http://www.microsoft.com/sql/reportingservices"><MoreInformation><Message>Unbekannter Fehler beim Reporting Services-Endpunkt für diese SharePoint-Website. Wenden Sie sich an den Administrator der SharePoint-Website.</Message></MoreInformation></RSError> --.

Do I indeed need to add this section to web.config? And where should I add this?

Answer 1

Try to add the following sections,

<add verb="*" path="Reserved.ReportViewerWebControl.axd" type = "Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

to system.web in section handlers

and add the following sections

<add name="ReportViewerWebControlHandler" preCondition="integratedMode" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

to system.webserver in section handlers

Actually the error message explains everything! Hope it helps.
