hi,
i'm trying to use an AjaxManager within  a User control's script using your recommended following code:
var ajaxManager = $find("<%= RadAjaxManager.GetCurrent(Page).ClientID
%>");
ajaxManager.AjaxRequest(args);
but everytime the page give me a 'System.NullReferenceException: Object reference not set to an instance of an object' error.
any advice of what could be the reason?

Hello Chani,

The proper link is here:
http://demos.telerik.com/aspnet-ajax/ajax/examples/manager/usercontrol/defaultcs.aspx

However, does using the following syntax, makes a difference?
C#
radMgr = $find("<%= RadAjaxManager.GetCurrent(this).ClientID %>");
