JQuery fancy Zoom effect for Image in | JQuery Increase Size of image when click on it in

Dec 28, 2011

In this article I will explain how to implement fancy zoom effect for image when we click on particular image using JQuery in

In previous post I explained about
JQuery Image slideshow gallery to display images slideshow. Now in this article I will explain how to increase size of image or implement zoom effect for image when we click on particular image in 
In some of websites generally we will see different types of image effect like whenever we click on image that will open with zoom effect. After seen that I decided to write post to use JQuery plugin to implement beautiful Zoom effect for images in 

To implement this one I am using  previous post insert and display images from folder based on imagepath in database because in that post I explained clearly how to insert images into our project folder and insert images path into database and display images in gridview from images folder based on Images path in database.
To implement image Zoom effect first design table in your database as shown below
Column Name
Data Type
Allow Nulls
int(set identity property=true)

After completion of table creation Open Visual Studio and create new website after that right click on your website and add new folder and give name as SlideImages because here I used same name for my sample if you want to change folder name then you need to change the Slideimages folder name in your code behind also after that write the following code in your aspx page  

<html xmlns="">
<title>jQuery Fancy Zoom plugin</title>            

<!-- required -->
<script type="text/javascript" src="js/jquery.js"></script>
<!-- optional -->
<script type="text/javascript" src="js/jquery.shadow.js"></script>
<script type="text/javascript" src="js/jquery.ifixpng.js"></script>
<script type="text/javascript" src="js/jquery.fancyzoom.min.js"></script>

<script type="text/javascript">
$(function() {
$('#demo > a:first').fancyzoom({ Speed: 400, showoverlay: false });
$('#demo > a:last').fancyzoom({ Speed: 400, showoverlay: false });
$('#nooverlay').fancyzoom({ Speed: 400, showoverlay: false });

<style type="text/css">
A IMG {border:0;}
margin:0 auto;
border:1px solid #000;
padding: 0px 20px 40px 20px;      
h2{font-size:16px;border-bottom:1px solid #CCC;margin-top:40px;}
h3{font-size:14px;border-bottom:1px solid #CCC;margin-left:40px;}
#demo A {
#demo  ul {text-align:left;color:#000;}
<form id="form1" runat="server">
<div id="demo">
<table align="center">
<td colspan="2" height="100"></td>
Upload Image:
<asp:FileUpload ID="fileuploadimages" runat="server" />
Enter Image Desc:
<asp:TextBox ID="txtDesc" runat="server"></asp:TextBox>
<asp:Button ID="btnSubmit" runat="server" Text="Submit" onclick="btnSubmit_Click" />
<td colspan="2">
<asp:DataList ID="dlImages" runat="server" RepeatColumns="3" CellPadding="5">
<asp:Image ID="Image1" class="fancyzoom" ImageUrl='<%# Bind("ImageName", "~/SlideImages/{0}") %>' alt='<%#Eval("Description") %>' runat="server" Width="112" Height="84" />
<ItemStyle BorderColor="Brown" BorderStyle="dotted" BorderWidth="3px" HorizontalAlign="Center"
VerticalAlign="Bottom" />
<br />
If you observe above code in header section I added some of script files and css file by using those files we will get Zoom effect for images. To get those files download attached sample code and use it in your application.

Another thing here we need to know is

<asp:Image ID="Image1" class="fancyzoom" ImageUrl='<%# Bind("ImageName", "~/SlideImages/{0}") %>' alt='<%#Eval("Description") %>' runat="server" Width="112" Height="84" />
In above tag I added class="fancyzoom" this class is used to active Zoom effect for image and alt attribute is used to display image caption.

After completion of aspx page design add following namespaces in code behind

C# Code

using System;
using System.Data;
using System.Data.SqlClient;
using System.IO;
After add namespace write the following code

SqlConnection con = new SqlConnection("Data Source=SureshDasari;Initial Catalog=MySampleDB;Integrated Security=true");
protected void Page_Load(object sender, EventArgs e)
if (!IsPostBack)
protected void BindDataList()
//Query to get ImagesName and Description from database
SqlCommand command = new SqlCommand("SELECT ImageName,Description from SlideShowTable", con);
SqlDataAdapter da = new SqlDataAdapter(command);
DataTable dt = new DataTable();
dlImages.DataSource = dt;

protected void btnSubmit_Click(object sender, EventArgs e)
//Get Filename from fileupload control
string filename = Path.GetFileName(fileuploadimages.PostedFile.FileName);
//Save images into SlideImages folder
fileuploadimages.SaveAs(Server.MapPath("SlideImages/" + filename));
//Open the database connection
//Query to insert images name and Description into database
SqlCommand cmd = new SqlCommand("Insert into SlideShowTable(ImageName,Description) values(@ImageName,@Description)", con);
//Passing parameters to query
cmd.Parameters.AddWithValue("@ImageName", filename);
cmd.Parameters.AddWithValue("@Description", txtDesc.Text);
//Close dbconnection
txtDesc.Text = string.Empty;

Imports System.Data
Imports System.Data.SqlClient
Imports System.IO

Partial Class _Default
Inherits System.Web.UI.Page
Private con As New SqlConnection("Data Source=SureshDasari;Initial Catalog=MySampleDB;Integrated Security=true")
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
If Not IsPostBack Then
End If
End Sub
Protected Sub BindDataList()
'Query to get ImagesName and Description from database
Dim command As New SqlCommand("SELECT ImageName,Description from SlideShowTable", con)
Dim da As New SqlDataAdapter(command)
Dim dt As New DataTable()
dlImages.DataSource = dt
End Sub

Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As EventArgs)
'Get Filename from fileupload control
Dim filename As String = Path.GetFileName(fileuploadimages.PostedFile.FileName)
'Save images into SlideImages folder
fileuploadimages.SaveAs(Server.MapPath("SlideImages/" & filename))
'Open the database connection
'Query to insert images name and Description into database
Dim cmd As New SqlCommand("Insert into SlideShowTable(ImageName,Description) values(@ImageName,@Description)", con)
'Passing parameters to query
cmd.Parameters.AddWithValue("@ImageName", filename)
cmd.Parameters.AddWithValue("@Description", txtDesc.Text)
'Close dbconnection
txtDesc.Text = String.Empty
End Sub
End Class
Now run your application and enter images description and upload some of the images using upload control after that your page should be like this 

Now click on any image automatically image will display with zoom effect. Check the below demo
