Microsoft ReportViewer Web Control Requiring a ScriptManager

Question

I'm trying to render the report viewer programmatically within a custom Page placed in an IHttpHandler context

ReportViewer rv = new ReportViewer();
ReportDataSource rds = new ReportDataSource();
rds.Name = "Report";
rv.LocalReport.ReportPath = "Report.rdlc";

rds.Value = SomeReportObject;

rv.LocalReport.DataSources.Add(rds);
rv.LocalReport.Refresh();

ScriptManager scriptHandler = new ScriptManager();
MyPage p = new MyPage();
p.Controls.Add(scriptHandler);
p.Controls.Add(rv);

using (TextWriter myTextWriter = new StringWriter())
        {
            using (HtmlTextWriter myWriter = new HtmlTextWriter(myTextWriter))
            {
               p.RenderControl(myWriter);
            }
        }

Although I have the ScriptManager added to the page but the runtime complains that the ReportViewer needs one, it throws the following exception at p.RenderControl(myWriter) line

The Report Viewer Web Control requires a System.Web.UI.ScriptManager on the web form.

And this is the MyPage Class

public class MyPage : Page
{

    public override void VerifyRenderingInServerForm(Control control)
    {
        //Empty Method
    }

    public override bool EnableEventValidation
    {
        get { return false; }
        set { /* Do nothing */}
    }
}

Any help would be very appreciated. This is done on .NET 4 and I'm using ReportViewer 2010.

Many thanks,

Maya.

Answer 1

just drag on the ScriptManager control under AJAX Extensions and it should work

In the aspx:

<form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
    <rsweb:ReportViewer ID="rptViewer" runat="server" Width="100%">
    </rsweb:ReportViewer>
</form>  

It worked for me, so I hope it helps everyone.
