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="*" 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.

If you are using IIS 7.x or greater, then the handler ref needs to go under a new section of your web.config file and should look like this:

HTML

<system.webserver>
    <validation validateintegratedmodeconfiguration="false" />
    <handlers>
      ...
      <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" />
    </handlers>
    <modules>
    ...
    </modules>
</system.webserver>

I was also facing same problem of report viewer not displaying. After setting display property from browser i got my error as "Report Viewer Configuration error".

I have found that for some parameter i am sending incorrect values i.e. "string .empty". I changed my code to send some value or null to parameter. Now my report is displaying properly. I have resolved my issue by sending correct report parameter values to report. Don't miss any parameter to assign proper values or null.

you can use

	<system.webServer>
		
		
	
		<handlers accessPolicy="Read, Script">

<add name="ReportViewerWebControlHandler" preCondition="integratedMode" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
<add name=".att" path="*.att" verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework64\v2.0.50727\aspnet_isapi.dll" resourceType="File" preCondition="classicMode,runtimeVersionv2.0,bitness64" />
<add name=".htm" path="*.htm" verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework64\v2.0.50727\aspnet_isapi.dll" resourceType="File" preCondition="classicMode,runtimeVersionv2.0,bitness64" />
		
	</handlers>

	</system.webServer>
