未定义PageMethods

Question

I am setting up PageMethods to access server side code using javascript. I am receiving the error "PageMethods is not defined" when i debug using firebug. the server side code is not being fired as well.

I have setup my script manager "EnablePageMethods" to true. My method is public & static and it has the WebMethod attribute set up as well. Still i m receiving the above error. Can it be because of the script manager being in a top level master page which has two child master pages and then my page is called:

i.e.

Main Master Page (with script manager) -> Primary master page -> Secondary master page -> My page -> My User control (having the WebMethod)

Is it possible tht the hierarchy is causing this issue?

This is the webmethod

 [System.Web.Services.WebMethod]
public static void AddNote(string t)
{
    int propid = 1; 
    if (propid > 0)
    {
     //Call my method
    }
}

this is my javascript code:

  function editNodes(t) {
    alert('test1');
    alert(t);
    PageMethods.AddNote(t,OnSuccess,OnFailure);
    alert('method called');
}
function OnSuccess() { 
    alert('Success'); 
    if (!navigator.appName == 'Microsoft Internet Explorer') {
        window.location.href = window.location.href;
    }

}
function OnFailure(error) {
    alert('Error:' + error);
}    

this is where I am calling it:

   <a href="#" class="btngeneral" onclick="javascript:editNodes(2);">Save</a>

As far as I understand, PageMethods on usercontrol is not supported and threads below seem to confirm that

ASP.NET AJAX Page Methods from UserControl

But I think there could be a workaround (not sure if that's efficient in your scenario). You can write a OneLine PageMethod in page's code behind which would intern call the Controls Page method. Now you can invoke your page's method from aspx and all set to go.

Or you may use ths alternative Alternate way to use page method inside user control asp.net
