reportviewer 11无法正常工作Visual Studio 2012

Question

I am using Visual Studio 2012 with Reportviewer 11 and nothing shows up at the run time. I have checked the web.config file, Ref assemblies , IIS & setting (adding all the handlers and changing the app domain), added the assembly refrences on aspx page. But still nothing comes up. When check the view source it says Report Viewer Configuration 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.

which I have already done :(

It also gives me an error : Your browser does not support scripts or has been configured not to allow scripts.

Any Help appreciated . Thank you .

Here is the code:

<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>


    <add assembly="Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845DCD8080CC91"/>
    <add assembly="Microsoft.ReportViewer.Common, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845DCD8080CC91"/>


<handlers>
  <remove name="WebServiceHandlerFactory-Integrated"/>

  <remove name="ScriptResource"/>
  <add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

</handlers>

Here is code behind: var query = (from p in db.PurchaseOrders where p.POID == yourValue select new { PurchaseOrderNumber = p.PurchaseOrderNumber, ..........

                         });

            ReportViewer1.LocalReport.ReportPath = "App_Data/POReport.rdlc";
            ReportViewer1.LocalReport.DataSources.Clear();
            ReportDataSource rdS = new ReportDataSource("PODataset", query.ToList());
            ReportViewer1.LocalReport.DataSources.Add(rdS);
            ReportViewer1.DataBind();
            ReportViewer1.LocalReport.Refresh();

Here is the aspx code

   <br />

    <rsweb:ReportViewer ID="ReportViewer1" runat="server" Font-Names="Verdana" Font-Size="8pt" WaitMessageFont-Names="Verdana" WaitMessageFont-Size="14pt" AsyncRendering ="false">
        <LocalReport ReportEmbeddedResource="EDICheckerTest/App_Data/POReport.rdlc">

        </LocalReport>
    </rsweb:ReportViewer>

I have a similar problem. VS 2012 project with ms report. Was working (using pdf and no viewer control) using version 10. Switched to version 11 over error messages when i attempted to add a viewer control. Now it doesn't render, I just get the following message. However, the entry that is indicated in the message is already in web.config (pasted it under the entry that was already there and it matches char for char)

I did notice that even though both reportviewer.common and webforms are in my assembly cache, There is no reportviewer.common dll in my Visual Studio 11\\reportviewer folder.

Report Viewer Configuration 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
