ASP.NET C# Method call using AJAX jQuery

Hi Friends,

In this article I will show you how to call an ASP.NET C# method (Web Method) using jQuery.

Step 1: Create a Web Application

Step 2: In WebForm1.aspx include jQuery file as given below. If you do not have jQuery file, you can download the latest files from

<script src="Scripts/jquery-1.4.1.js" type="text/javascript"></script>

Step 3: 

In code behind page (WebForm1.aspx.cs) create a web method to return some data as given below. Make sure to add the attribute [WebMethod()] to the function. You have to include the namespace System.Web.Services. (using System.Web.Services;)

Add a web method in your page as mentioned below.

        public static string GetAllEmpName()
        Employee objEmployee = new Employee { Name = "Sujeet", EmpSal = "50,000", Id = 82375 };

            return "Parameter sent to server from client side as " +
           "follows:<br/>First Name => " +
           objEmployee.Name + "<br/>Emp Sal => " +
           objEmployee.EmpSal + "<br/>Id=> " +
           objEmployee.Id + "<br/>Address => " + objEmployee.Address;

This method returns All Employees from database or collection

Step 4

We will use a jQuery "Ajax" method to call, page methods.

<script type="text/javascript">
    function () {
    try {
    function () {
    type: "POST",
    url: "AJAXCalling.aspx/GetAllEmpName",
    data: "{}",
    contentType: "application/json;charset=utf-8",
    dataType: "json",
    async: true,
    cache: false,
    success: function (msg) {

        $('#myDiv3').text(msg.d); alert(msg.d);
    error: function (x, e) {
        alert("The call to the server side failed. " + x.responseText);
        return false;

    catch (err) {

Step 5:

In the Html page we will add div and button like

   <asp:Button ID="btnTest3" runat="server" Text="Click Me"   />
<div id="myDiv3" style="font-family:Arial; color: Red;"/>

Run the application and click the button, you can see that the webmethod is called and data is returned.

Happy Programming!!
