Step 1: First, We start by creating an Empty asp.net web site in Visual Studio .NET 2013.
Note: Also include jQuery files using Nuget Package Manager
Step 2: Add a new web page name "Default.aspx" with the following codes:-
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title></title>
<script src="Scripts/jquery-2.1.4.js" type="text/javascript"></script>
<style type="text/css">
.loader
{
display: none;
background-color: Red;
width: 100px;
}
</style>
<script language="javascript" type="text/javascript">
$(document).ready(function () {
$("#btnLoad").click(function (e) {
e.preventDefault();
$("#gvData").html("");
$("#loader").show();
sendData();
});
});
function sendData() {
var loc = window.location.href;
loc = (loc.substr(loc.length - 1, 1) == "/") ? loc + "Jquery_Progress.aspx" : loc;
$.ajax({
type: "POST",
url: loc + "/GetAllProducts",
contentType: "application/json;charset=utf-8",
dataType: "json",
success: function (msg) {
$("#loader").hide();
$("#gvData").html(msg.d);
},
error: function () {
alert("An unexpected error has occurred during processing.");
}
});
}
</script>
</head>
<body>
<form id="form1" runat="server">
<asp:Button ID="btnLoad" runat="server" Text="LoadProduct" /><br />
<div id="gvData">
</div>
<div id="loader" class="loader">
Loading....</div>
</form>
</body>
</html>
Step 3: Add the following codes in code behind of default.aspx
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.Services;
using System.Web.Script.Services;
using System.Web.Script.Serialization;
using System.Text;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
[WebMethod]
[ScriptMethod]
public static string GetAllProducts()
{
//Comment below line for production server
System.Threading.Thread.Sleep(3000);
StringBuilder sb = new StringBuilder();
JavaScriptSerializer json = new JavaScriptSerializer();
List<Product> products = ProductDAL.GetProducts();
json.Serialize(products, sb);
return sb.ToString();
}
}
public class Product
{
public int ProductID { get; set; }
public string ProductName { get; set; }
public string Description { get; set; }
}
public class ProductDAL
{
public static List<Product> GetProducts()
{
return new List<Product>()
{
new Product() {ProductID = 1, ProductName = "Apple", Description = "Desc01 Goes here"},
new Product() {ProductID = 2, ProductName = "Banana", Description = "Desc02 Goes here"},
new Product() {ProductID = 3, ProductName = "Rice", Description = "Desc03 Goes here"},
new Product() {ProductID = 4, ProductName = "Grapes", Description = "Desc04 Goes here"},
