JQuery Show Large Image Preview When Hover On Link In Asp.Net

Sep 17, 2012

In this article I will explain how to show large image preview when hover on link or image using JQuery in


In previous article I explained Generate thumbnail from images in, Generate thumbnails from YouTube videos using JQuery and many articles relating to JQuery,, SQL Server etc. Now I will explain how to show large image preview when hover on link or image using JQuery in

To implement this concept first create new web application >> Right click on your application >> Select Add New Folder and Give name as Images >> Once folder created place some images in folder to show preview of images when hover on link using JQuery in

After completion of folder creation and insertion of images in folder write the following code in your aspx page

<html xmlns="">
<head id="Head1" runat="server">
<title>Show Image Preview when hover on Link using jQuery</title>
<script type="text/javascript" src="">
<script type="text/javascript" language="javascript">
$(document).ready(function() {
// Configuration of the x and y offsets
function ShowImagePreview() {
xOffset = -20;
yOffset = 40;

$("a.preview").hover(function(e) {
this.t = this.title;
this.title = "";
var c = (this.t != "") ? "<br/>" + this.t : "";
$("body").append("<p id='preview'><img src='" + this.href + "' alt='Image preview' />" + c + "</p>");
.css("top", (e.pageY - xOffset) + "px")
.css("left", (e.pageX + yOffset) + "px")

function() {
this.title = this.t;

$("a.preview").mousemove(function(e) {
.css("top", (e.pageY - xOffset) + "px")
.css("left", (e.pageX + yOffset) + "px");

<style type="text/css">
border:3px solid #ccc;
box-shadow: 4px 4px 3px rgba(103, 115, 130, 1);
<form id="form1" runat="server">
<asp:DataList ID="dtlist" runat="server" RepeatColumns="4" CellPadding="5">
<asp:HyperLink ID="HyperLink1" class="preview" ToolTip='<%#Bind("Name") %>' NavigateUrl='<%# Bind("Name", "~/Images/{0}") %>' runat="server">
<asp:Image Width="100" ID="Image1" ImageUrl='<%# Bind("Name", "~/Images/{0}") %>' runat="server" />
<ItemStyle BorderColor="Brown" BorderStyle="dotted" BorderWidth="3px" HorizontalAlign="Center"
VerticalAlign="Bottom" />
Now add the following namespaces in code behind

C# Code

using System;
using System.Collections;
using System.IO;
After add namespaces write the following code in code behind

protected void Page_Load(object sender, EventArgs e)
if (!IsPostBack)
protected void BindDataList()
DirectoryInfo dir = new DirectoryInfo(MapPath("Images"));
FileInfo[] files = dir.GetFiles();
ArrayList listItems = new ArrayList();
foreach (FileInfo info in files)
dtlist.DataSource = listItems;

Imports System.Collections
Imports System.IO
Partial Class VBCodeSamples
Inherits System.Web.UI.Page
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()
Dim dir As New DirectoryInfo(MapPath("Images"))
Dim files As FileInfo() = dir.GetFiles()
Dim listItems As New ArrayList()
For Each info As FileInfo In files
dtlist.DataSource = listItems
End Sub
