O manipulador HTTP do Report Viewer Web Control não foi registrado no arquivo web.config do aplicativo

    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

Este erro está chegando. Eu já mencionei esta linha no handler http, mas ainda recebendo este erro

<add path="Reserved.ReportViewerWebControl.axd" verb="*"   type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=8.0.0.0,    Culture=neutral, PublicKeyToken=0000000000000000" validate="false" />

minha marcação de página html é como segue

<%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
    Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %>

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:Button ID="btnsubmit" runat="server" OnClick="GenerateReportButton_Click" />
    <rsweb:ReportViewer ID="ReportViewer1" runat="server">
    </rsweb:ReportViewer>
</asp:Content>

A seção de assemblies de configuração da Web é a seguinte:
