RDLC : Web.config Settings for ReportViewer

We, .Net Developers always do many kind of reports using RDLC . But while developing , we get the below error If we do not add web.config entries correctly .

We may get runtime error like below :::

The Report Viewer Web Control HTTP Handler has not been registered in the application’s web.config file

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

To resolve this issue , add these below Nodes to Web.Config.

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



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

Cheers 🙂
