$find failing to find Ajax control in master page

[PaulMrozowski]

 I have a master page which has an instance of the RadAjaxManager on it (Named RadAjax). I have a content page which has options to open a window (RadWindow). When you click on a button on this open window it injects some JavaScript that is supposed to force a refresh of the calling page, then close itself. I'm in the process of trying to update to the AJAX version of the controls and things aren't quite working.

In my first content page, I have this JavaScript function:

var ajaxManager = $find("<%= Telerik.Web.UI.RadAjaxManager.GetCurrent(Page).ClientID %>");
ajaxManager.ajaxRequest("Rebind");

I know this function is getting called correctly from my "pop in" form. However, ajaxManager is null so the rebind never occurs. I looked at the generated JS in the page and the markup is getting translated to this, which looks correct. What am I missing?

var ajaxManager = $find("ctl00_RadAjax");

Hi Paul,

Please try to use the code below instead the one you provided and let me know if this helps:

$find("<%= RadAjax.GetCurrent(Page).ClientID %>").ajaxRequest("Rebind");

Unfortunately, it doesn't. Now the page fails with a compilation error - "The name 'RadAjax' does not exist in the current context" (which it doesn't - RadAjax is on the master page).

 I just added a property to my content page that looks at the master page, does a FindControl to get the reference to my RadAjaxManager and returns it directly. Then I modifed my JS code to use this new property to reference the ClientID. That seems to work.
