c# - Call Webmethod in Usercontrol.cs from Usercontrol.ascx javascript -

-

i have usercontrol , in have javascript function makes call webmethod.

<%@ control language="c#" autoeventwireup="true" codefile="leftmenu.ascx.cs" inherits="usercontrols_leftmenu" %>  <script type="text/javascript">  function getrealtimecount() {     pagemethods.countofmenus('', '', getcountofmenus_success, getcountofmenus_fail); }

my webmethod code is

[system.web.services.webmethod] public static string countofmenus(string startdate, string enddate) {     //code here }

but when run code, gives me javascript error, countofmenus undefined. know error because cant find method in current page want access method in usercontrol.cs. cant write webmethod in every page have lots of pages usercontrol used. there way through can call method of usercontrol.cs in javascript?

i solved below method

javascript :

function getrealtimecount(startdate, enddate) {     var xmlhttp;     if (window.xmlhttprequest) {// code ie7+, firefox, chrome, opera, safari         xmlhttp = new xmlhttprequest();     }     else {// code ie6, ie5         xmlhttp = new activexobject("microsoft.xmlhttp");     }     var url = "default.aspx?method=countofmenus&sd=" + startdate + "&ed=" + enddate;     xmlhttp.open("get", url, false);     xmlhttp.send(null);     document.getelementbyid("count").innerhtml = xmlhttp.responsetext; }

code behind:

protected void page_load(object sender, eventargs e) {     if (request.querystring["method"] == "countofmenus")         {             response.cache.setcacheability(httpcacheability.nocache);             getcount(request.querystring["sd"], request.querystring["ed"]);         }     }      private void getcount(string startdate, string enddate)     {         response.clear();          // code count          response.write(count.tostring());         response.end();     }
