popupcontrolextender with radajaxscriptmanager throws 'null' is null or not an object on page load

[Hrushikesh Mokashi]

Hi,

I am using popupcontrolextender in my aspx page. i am opening this page from one of my contentpage.
when this pages pops up i see a java script error say 'null' is null or not an object on page load and when i try to debug this it redirects me on debug page and code where the error occured is

function() {var fn = function() {$get('ctl00_ScriptManager1_HiddenField').value += ';;System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35:en-US:0d787d5c-3903-4814-ad72-296cea810318:52817a7d:67c678a8;Telerik.Web.UI, Version=2008.2.1001.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4:en-US:9638cb27-0c96-4947-a8f4-d97afe664a61:393f5085:34f9d57d:9703c1f0:a3f85c94:f2a57eb7:526d426:80c4ad6d:527acb41:a9723048:39249aa4:577694e5:665c7bcf:c6335cbd;AjaxControlToolkit, Version=1.0.10123.0, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e:en-US:16d938d8-51f5-4794-8714-fcfbd6996217:e2e86ef9:c59c074c:1df13a87:c4c00916:ba594826:c76f1358';Sys.Application.remove_load(fn);};Sys.Application.add_load(fn);})();

even though i set EnablePartialRendering='false' it shows same error
same is working on my contentpage where my radscriptmanager is on my masterpage without this error.
Radscriptmanager code on masterpage is as below

<telerik:RadScriptManager ID="ScriptManager1" Runat="server"
          EnableTheming="True" OutputCompression="AutoDetect" EnablePageMethods="true" >
         </telerik:RadScriptManager>

and the same is on my new aspx page that i am calling from a contentpage and facing jscript error is
<telerik:RadScriptManager ID="ScriptManager2" Runat="server" EnableTheming="True"
            OutputCompression="AutoDetect" EnablePageMethods="true" EnablePartialRendering="false">
         </telerik:RadScriptManager>
<telerik:RadScriptManager ID="ScriptManager1" Runat="server"
          EnableTheming="True" OutputCompression="AutoDetect" EnablePageMethods="true" >
         </telerik:RadScriptManager>

please help me to resolve this issue.
Thanks in advance.
