  Add ReportViewer httphandler and entire website errors

  Oct 20, 2010 10:07 PM|LINK

  I have a site thats working fine - I added a page with a reportviewer control and get the error message

  
  

  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=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> to the system.web/httpHandlers section of the web.config file.

  
  

  I added this to the system.web section of web.config, and when I do - the entire site no longer works, I get a "500 - Internal server error." 

  
  

  The web.config currently reads:

  
  

  <?xml version="1.0"?>
  <configuration>
  	<connectionStrings>
  		<add connectionString="Server=server;
           Database=database;
           User ID=user;
           Password= password"
           name="ConnectionString"
           providerName="System.Data.SqlClient"/>
  	</connectionStrings>
  	<system.web>
  		<customErrors mode="Off"/>
  		<compilation debug="true" strict="false" explicit="true" targetFramework="4.0">
  			<assemblies>
          <add assembly="Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/>
          <add assembly="Microsoft.ReportViewer.Common, Version=9.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/>
        </assemblies>
      </compilation>
      <!--<httpHandlers>
        <add verb="*" path="Reserved.ReportViewerWebControl.axd" type = "Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
      </httpHandlers>-->
    </system.web>
  	<system.net>
  		<mailSettings>
  			<smtp from="email">
  				<network defaultCredentials="false" host="host" password="password" userName="username"/>
  			</smtp>
  		</mailSettings>
  	</system.net>
  </configuration>

  
  Anyone have any advice as to why this happens?

  You need to install the Microsoft Report Viewer Redistributable 2008 on your server available at

  http://www.microsoft.com/downloads/en/details.aspx?FamilyID=CC96C246-61E5-4D9E-BB5F-416D75A1B9EF

  The 'Ver 9' in your screen shot indicates you are using VS 2008

  This will insert the following DLL's in the server GAC

  1. Microsoft.ReportViewer.Common.dll

  2.  Microsoft.ReportViewer.ProcessingObjectModel.dll

  3. Microsoft.ReportViewer.WebForms.dll

  Alternatively you could just copy these Dlls to your bin

  The above installation will also provide you with

  Microsoft.ReportViewer.WinForms.dll

  You will need this should you create a desktop application.
