I have found multiple threads on this issue but none of the solutions work for me.

I am using the solution from here:
http://www.telerik.com/ClientsFiles/207185_printradgrid-ignorepaging.zip

to print a grid with paging temporarily disabled. However, this line always returns a null:

var radGrid = $find(radGridId);

I've tried using

var

grd = $find("<%= radgrdMyPrograms.ClientID %>");

to no avail. I always get a null and then the .get_element().outerHTML fails and, of course, the

.get_masterTableView().fireCommand(

'EnablePaging', '') also fails.

here is my entire .aspx:

<asp:Content ID="Content1" ContentPlaceHolderID="MasterContentPlaceHolder" Runat="Server">

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

<script type="text/javascript">

function PrintRadGrid() {

var grd = $find("<%= radgrdMyPrograms.ClientID %>");

var previewWnd = window.open('about:blank', '', '', false);

var sh = '<%= ClientScript.GetWebResourceUrl(radgrdMyPrograms.GetType(),String.Format("Telerik.Web.UI.Skins.{0}.Grid.{0}.css",radgrdMyPrograms.Skin)) %>';

var styleStr = "<html><head><link href = '" + sh + "' rel='stylesheet' type='text/css'></link></head>";

var htmlcontent = styleStr + "<body>" + grd.get_element().outerHTML + "</body></html>";

previewWnd.document.open();

previewWnd.document.write(htmlcontent);

previewWnd.document.close();

previewWnd.print();

previewWnd.close();

grd.get_masterTableView().fireCommand('EnablePaging', '');

}

</script>

</telerik:RadScriptBlock>

<style type="text/css">

.RadMenu .rmGroup .rmText {

font-size: x-small;

width: 110px; }

</style>

<table width="100%" cellpadding="0px" cellspacing="0px" style="padding-bottom:4px;">
