C# Web method is not calling in javascript

There are few rules for ajax to work with asp.net.

• Your WebMethod should be

  public

  and

  static

  .
• If your WebMethod expects some parameter(s) than these parameter(s) must
  be passed as

  data

  in ajax.
  
• Name of parameter(s) should be

  same

  in

  WebMethod

  and in

  data

  part
  of ajax.
• Data passed from ajax should be in

  json string

  .For this you can use
  

  JSON.stringify

  or you will have to surround the

  values

  of parameter(s)
  in

  quotes

  .
  

Please check the below sample ajax call

function CallAjax()    {        $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "Default.aspx/CallAjax", data: JSON.stringify({ name: "Mairaj", value: "12" }), dataType: "json", async: false, success: function (data) {     //your pre }, error: function (err) {     alert(err.responseText); }        });    }[WebMethod]public static List<string> CallAjax(string name,int value){    List<string> list = new List<string>();    try    {        list.Add("Mairaj");        list.Add("Ahmad");        list.Add("Minhas");    }    catch (Exception ex)    {    }    return list;}

EDIT

If you use

GET

in ajax than you need to enable your webmethod to be called
from

GET

request. Add

[System.Web.script.Services.scriptMethod(UseHttpGet =true)]

on top of WebMetod

[System.Web.Services.WebMethod][System.Web.script.Services.scriptMethod(UseHttpGet = true)]public static int ItemCount()
