Error while accessing ASP.Net Page Label control in WebMethod during AJAX PageMethods call

Hi,

gud evening Khan br,

i found Your Article from link :

http://www.aspsnippets.com/Articles/Calling-server-side-function-from-JavaScript-in-ASP.Net.aspx

that explains how to call server-side Method from javascript,

i used your code, my server-side function is static, public, and also i addeed

[System.Web.Services.WebMethod]  and

 bt at run time the Error is PageMethods is undefined

i write:

PageMethods.Alpha();

Alpha is my server-side Method of void type and have no arguments,

i have applied this code in user Control

   [System.Web.Services.WebMethod]     public static void Alpha()     {

        try         {             Page pg1=new Page();             Label Msg = (Label)pg1.FindControl("lblMsg");             Msg.Text = "Function Called";             }         catch (Exception ex)         {

            //lblMsg.Text = ex.Message.ToString();         }

    }
