解决方案

我有非常相同的问题。发生了什么事，我把报告装载程序上的Page_Load，如果不把它包在（！的IsPostBack）。该做的ReportViewer一个POST到页面，这是触发的Page_Load和重装的报告，不知何故搞乱它。把一切都放到里面之后，如果（！的IsPostBack），它的工作就像一个魅力。

    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

This error is coming . I have already mentioned this line in http handler but still getting this error

<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" />

my html page markup is as follow

<%@ 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>

Web config assemblies section is as follows :

<assemblies>
    <add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
    <add assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

</assemblies>

解决方案

I was having the very same problem. What happened was I put the Report loading routine on Page_Load, and didn't wrap it in if (!IsPostBack). The ReportViewer makes a POST to the page, and that was triggering Page_Load and reloading the report, somehow messing it up. After putting everything inside if (!IsPostBack), it worked like a charm.
