Visual Studio 中的报告查看器配置错误

Question

I want to add some reports in my project and when I am going to show them that time I got following Error

The Report Viewer Web Control HTTP Handler has not been registered in the application's web.config file. Add to the system.web/httpHandlers section of the web.config file, or add to the system.webServer/handlers section for Internet Information Services 7 or later.

and my Web-Config file is looks like following: -

<system.web>
<compilation debug="true" targetFramework="4.5">
  <assemblies>
    <add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>

  </providers>
</sessionState>
 </system.web>

I am not see any 'httpHandlers' portion here.. how can I overcome from this problem ?? After add 'httpHandlers' portion manualy still I get same error

<httpHandlers>
  <add verb="*" path="Reserved.ReportViewerWebControl.axd" type =   "Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
</httpHandlers>

将此部分添加到我的 Web 配置中，最后我通过以下方式解决了这个问题：-

<system.webServer> <!-- Add this to here.... --> <validation validateIntegratedModeConfiguration="false"/> <handlers> <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" /> </handlers> </system.webServer>
