using $find method in DNN module

[JC Wu]

I have a program that needs to call ajaxRequest from client side.
When I use this code in any aspx page, it works fine.
But when I put it into a DNN module,the $find method always return null.
Is there any difference in DNN module?

var ajaxManager = null;

        function pageLoad() {
            if (ajaxManager == null) {
                ajaxManager = $find("<%= RadAjaxManager1.ClientID %>");
            }
        }
        function SuccessHandler(privateToken, alias, message) {
            var datetime = new Date();
            ajaxManager.ajaxRequest("(" + datetime.toLocaleTimeString() + ")");
        }

Hi JC Wu,

Have you tried with:

ajaxManager = $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>");

In a DNN module, you may not (and should not) have RadAjaxManager placed in the module. It needs to go in a master page or an ASPX page if no master. Therefore, we use the static RadAjaxManager.GetCurrent() method to get a reference to the current instance of the manager.

Thanks for reply.
I have tried

ajaxManager = $find("<%=(this.Page.FindControl("RadAjaxManager1") as RadAjaxManager).ClientID%>");

and

ajaxManager = $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>");

In first case, it gets null value when first time open the page.
In second case,it works fine.
