Ajax Method Using AjaxPro

Here i am explaining how we can use an AjaxMethod using AjaxPro Dll through which we can call Server sid methods from javascript.

Download AjaxPro Dll from

First Add reference to AjaxPro Dll,then create a Page.Code behind look like this,

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using AjaxPro;

public partial class _Default : System.Web.UI.Page
protected void Page_Load(object sender, EventArgs e)

if (!IsPostBack)


public int Sum(int a, int b)
return a + b;


Here in the above code Sum(int a, int b) is the AjaxMethod.Before using this we have to Register the Type for Ajax ie,Utility.RegisterTypeForAjax(typeof(_Default));

After that Create a javascript method and we can call this AjaxMethod like,

_Default.Sum(10, 5).value.

So our javascript function looks like this,

function CalculateSum()
alert(_Default.Sum(10, 5).value);

Here you will get the sum of the two values in script.
Another important thing is while creating AjaxMethod,it should be a public Method.And pass parameters from javascript as the same datatype as in the Ajax Method.By using this we can reduce unnecessary postback of the webpage.
