<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"
runat="server">
<title>jQuery show progress bar on button click asp.net</title>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.2.js"></script>
<style type="text/css">

{
background-color:#DC5807;

function GetData()
{
$.ajax({

contentType: "application/json;

url: "ShowLoadingImageonButtonClick.aspx/BindDatatable",
data: "{}",
dataType: "json",
success: function(data)
{
var theHtml = data.d;

$('#DisableDiv').html("");
},
error: function(result)

}
});
}
</script>
</body>
</html>

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)
{
}
[WebMethod]
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))
{
con.Open();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(dt);
}
}
gv.HeaderStyle.CssClass = "sample";
gv.DataSource = dt;
gv.DataBind();
gv.RenderControl(htmlWriter);
return stringWriter.ToString();
}
|
VB.NET Code
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)
con.Open()
Dim da As New SqlDataAdapter(cmd)
da.Fill(dt)
End Using
End Using
gv.HeaderStyle.CssClass = "sample"
gv.DataSource = dt
gv.DataBind()
gv.RenderControl(htmlWriter)
Return stringWriter.ToString()
End Function
End Class

This program is also showing error. Is there any other problem. Please help.
Hi Suresh,
Nice article. We can do this by using ajaxStart and ajaxComplete events also. These events will be more accurate than timeout function.

Hello,
Thanks for your posts, Can we do this without
setTimeout(function() { GetData() }, 1000)
})
because we cannot judge the time, right. is there any code please suggest me.
what if any error occurs? Should the loading div be visible then?
