    I have a problem with $find("RadAjaxManager1") returning null.
    This seems to happen because $find("RadAjaxManager1") is called at page load and apparently the javascript object for the RadAjaxManager is not yet created.
    Using a function that calls itself after 300 milliseconds if $find("RadAjaxManager1") returns null until $find("RadAjaxManager1") does return the desired object helps.

    Is there another way to force calls like $find("RadAjaxManager1") to wait until after the RadAjaxManager object is created?

    Hello mink,

    In order to get the client side object of RadControls on pageload, you can create function that uses the reserved name pageLoad (which fires when page loads) and in the handler you can access the client side object of RadAjaxManager. Give a try with this approach and see whether it is suitable for you.

        function pageLoad() { 
            var ajaxManager = $find('<%= RadAjaxManager1.ClientID %>'); 
            // Your code 

    Could you provide some more information about your scenario if this doesn't help?
