I am having an issue below while I am doing any postback event.

    Sys.InvalidOperationException: Could not find UpdatePanel with ID
    'ctl00_PageContent_rvReport_ReportViewer'. If it is being updated dynamically then it
    must be inside another UpdatePanel.

Here is my aspx code:

<tel:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">
        <AjaxSettings>
            <tel:AjaxSetting AjaxControlID="fbPrintBiomassReport">
                <UpdatedControls>
                    <tel:AjaxUpdatedControl LoadingPanelID="ApplicationWideLoadingPanel" ControlID="fbPrintBiomassReport" />
                </UpdatedControls>
            </tel:AjaxSetting>
        </AjaxSettings>
    </tel:RadAjaxManagerProxy>

<rfp:FormPanel ID="fpPrintReports" runat="server" Title="Biomass Report">
                <asp:UpdatePanel ID="upReportViewer" runat="server">
                    <ContentTemplate>
<rfp:FormButton runat="server" ID="fbPrintBiomassReport" Type="Print" Text="Print Report" OnClick="fbPrintBiomassReport_Click" />
                <asp:UpdatePanel runat="server" ID="rpViewer3">
                    <ContentTemplate>
                        <rsweb:ReportViewer ID="rvReport" runat="server" AsyncRendering="false" ShowParameterPrompts="false" Height="780px" Width="100%" ProcessingMode="Remote"></rsweb:ReportViewer>
                    </ContentTemplate>
                </asp:UpdatePanel>
            </rfp:FormPanel>

Here is my code behind script:

protected void fbPrintBiomassReport_Click(object sender, EventArgs e)
        {
            rvReport.Reset();
            rvReport.Visible = false;
            if (!string.IsNullOrEmpty(rcProjectGearCatch.SelectedValue))
            {
                List<ReportParameter> parameterList = new List<ReportParameter>();

                parameterList.Add(new ReportParameter("CatchID", rcProjectGearCatch.SelectedValue));
                rvReport.ServerReport.ReportServerCredentials = new SciCollReportServerCredentials();
                //rvReport.PageCountMode = Microsoft.Reporting.WebForms.PageCountMode.Actual;
                rvReport.ServerReport.ReportServerUrl = new Uri(ConfigurationManager.AppSettings["ReportServer"]);
                rvReport.ServerReport.ReportPath = "/" + ConfigurationManager.AppSettings["ReportsRootPath"] + "/SciColl/" + "BiomassReport";
                rvReport.ServerReport.SetParameters(parameterList);
                rvReport.ServerReport.Refresh();
                rvReport.Visible = true;
            }
        }

Has any of you known the solution for that? Please help. Thanks In advance.
