jQuery Display Progress Bar on Button Click in

Oct 6, 2013

Here I will explain how to use
jQuery to show progress bar on button click in with example in c#, or jQuery show loading image on button click in using c#,


In my previous article I explained
jQuery bind gridview in, Show progress bar during postbacks in, Bind dropdown in jQuery, Lightbox effect for login page and many articles relating to jQuery,, c#, Now I will explain how to show progress bar on button click using jQuery in

To implement this we need to write the code like as shown below in your aspx page

<html xmlns="">
<head id="Head1" runat="server">
<title>jQuery show progress bar on button click</title>
<script type="text/javascript" src=""></script>
<style type="text/css">
border:1px solid black;
<form id="form1" runat="server">
<div id="DisableDiv"> </div>
<input type="button" id="btnClick" value="Get Data" />
<div id="testdiv"></div>
<script type="text/javascript">
$(function() {
$('#btnClick').click(function() {
$('#DisableDiv').fadeTo('slow', .6);
$('#DisableDiv').append('<div style="background-color:#E6E6E6;position: absolute;top:0;left:0;width: 100%;height:300%;z-index:1001;-moz-opacity: 0.8;opacity:.80;filter: alpha(opacity=80);"><img src="loading.gif" style="background-color:Aqua;position:fixed; top:40%; left:46%;"/></div>');
setTimeout(function() { GetData() }, 1000)
function GetData()
type: "POST",
contentType: "application/json; charset=utf-8",
url: "ShowLoadingImageonButtonClick.aspx/BindDatatable",
data: "{}",
dataType: "json",
success: function(data) {
var theHtml = data.d;
error: function(result) {
Now add following namespaces in code behind

C# Code

using System;
using System.Data;
using System.Data.SqlClient;
using System.Web.Services;
using System.Web.UI;
using System.Web.UI.WebControls;
Once we add namespaces need write the code like as shown below

protected void Page_Load(object sender, EventArgs e)
public static string BindDatatable()
GridView gv = new GridView();
System.IO.StringWriter stringWriter = new System.IO.StringWriter();
HtmlTextWriter htmlWriter = new HtmlTextWriter(stringWriter);
DataTable dt = new DataTable();
using (SqlConnection con = new SqlConnection("Data Source=SureshDasari;Initial Catalog=MySampleDB;Integrated Security=true"))
using (SqlCommand cmd = new SqlCommand("select UserId,UserName,Location from UserInformation", con))
SqlDataAdapter da = new SqlDataAdapter(cmd);
gv.HeaderStyle.CssClass = "sample";
gv.DataSource = dt;
return stringWriter.ToString();

Imports System.Data
Imports System.Data.SqlClient
Imports System.Web.Services
Imports System.Web.UI
Imports System.Web.UI.WebControls

Partial Class VBCode
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
End Sub
<WebMethod()> _
Public Shared Function BindDatatable() As String
Dim gv As New GridView()
Dim stringWriter As New System.IO.StringWriter()
Dim htmlWriter As New HtmlTextWriter(stringWriter)
Dim dt As New DataTable()
Using con As New SqlConnection("Data Source=SureshDasari;Initial Catalog=MySampleDB;Integrated Security=true")
Using cmd As New SqlCommand("select UserId,UserName,Location from UserInformation", con)
Dim da As New SqlDataAdapter(cmd)
End Using
End Using
gv.HeaderStyle.CssClass = "sample"
gv.DataSource = dt
Return stringWriter.ToString()
End Function
End Class

Hi Suresh,

Nice article. We can do this by using ajaxStart and ajaxComplete events also. These events will be more accurate than timeout function.

what if any error occurs? Should the loading div be visible then?
