When I click next page in radgrid it shows the following error.

Cannot unregister UpdatePanel with ID 'ctl00$ContentPlaceHolder1$RadProduct$ctl00$ctl05$ctl01$grdStockPanel' since it was not registered with the ScriptManager. This might occur if the UpdatePanel was removed from the control tree and later added again, which is not supported.
Parameter name: updatePanel

ExportToExcel as CommandItemTemplate Issue

Hi. I have a radgrid with a command item template. I have Add New Record open a radwindow. I have an imagebutton for export to excel, and I set it up like the demo suggests (http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/pdfexport/defaultcs.aspx), but instead of exporting, it hides the command items. I am posting my code below. Could you please let me know what I am doing wrong?

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<script type="text/javascript">

function onRequestStart(sender, args) {

if (args.get_eventTarget().indexOf("excelExport") > 0) {

args.set_enableAjax(false);

}

function ShowInsertForm() {

var combo = $find("<%= RadComboBox1.ClientID %>");

var comboItem = combo.get_selectedItem();

if (!comboItem)

{

window.radopen("AddComment.aspx", "UserListDialog");

}

else {

window.radopen("AddComment.aspx?something=" + comboItem.get_value("something"), "UserListDialog");

}

return false;

}

function refreshGrid() {

$find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("Rebind");

}

</script>

<telerik:RadGrid ID="RadGrid1" runat="server" AllowFilteringByColumn="True"

AllowPaging="True" AllowSorting="True" GridLines="None" Skin="WebBlue"

</RowIndicatorColumn>
