Microsoft JScript runtime error: 'this.m_clientController' is null or not an object

Visual Studio 2008 and Report viewer 9.0 with Update Panel ( Neither the VS 2005 nor the VS 2008 version of the report viewer is supported with ASP.NET AJAX)

This kind of Error we can Handle just write a Trigger for that so there no Scope to Get error this kind of Error

 Place  RepoViewer in Update Panel and Write the Postback Trigger.

<cc1:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
       <asp:UpdatePanel ID="UpdatePanel1" runat="server">
         <Triggers >
            <asp:PostBackTrigger ControlID="btnGetReport" />
<asp:Button ID="btnGetReport" runat="server" Text="View Report"  
            onclick="btnGetReport_Click" />
     <rsweb:ReportViewer ID="MyReportViewer" runat="server" ProcessingMode="Remote" Width="900px"  >


  1. Thank you sir. You saved me hours and frustration.

  2. The Garcinia Cambogia is said to suppress a persons
    appetite. The majority of concocted foods don't include very much
    fiber. Together with all the different fat loss medications entering into the market--
    and quickening discussion-- some people are likewise resorting
    to diet supplement to aid weight loss.
