RadAjaxManager Master /content page

[p p]

I have a master page with RadAjaxManager and a content page with RadAjaxManagerProxy.
In the content page i try to make callback  request to server from client side like this:

var m = $find("<%=RadAjaxManager.GetCurrent(Page).ClientID %>");
m.ajaxRequest(eventArgs);

but "m" is allways null!

The script is placed inside of RadCodeBlock!
If you have any idea please share with me!

Hello,

Could you ensure that the RadAjaxManager on the Master page is placed after a ScriptManager or RadScriptManager?

Yes, it's placed after  a RadScriptManager.
Behind the code everything woks just fine:

RadAjaxManager manager = RadAjaxManager.GetCurrent(Page);

"manager" is valid and i don't have any problem.
My problem appear in javascript code  on client side.

Hello,

I am attaching a sample which is accessing the RadAjaxManager's client-side object in a content page. Take a look at it and let me know what differs in your case.

All the best,

If script code is placed in aspx file work  fine, but placed in separate file *.js  the error remain.
Any idea?

Hi,

In that case you need to store a variable with the RadAjaxManager's CleintID (say on the content page):
Content.aspx

<script type="text/javascript" language="javascript">
    var ajaxID = '<%=RadAjaxManager.GetCurrent(Page).ClientID %>'; //this variable will evaluate the ClientID
</script>

And then use it in your javascript file:
external js file

function getAjax()
{
    alert($find(ajaxID));
}

Best wishes,
