Change image on MouseHover using Jquery in asp.net

Introduction: In this article I try to explain how we can change the image on mouse hover using Jquery in asp.net.

Description:

In the previous article I have explained Zoom the image on mouse hover in asp.netGridview data control using Elevate Jquery and Zoom the image inside onMouseHover in Asp.net Gridview control using Magnify Jquery.

We normally saw change image functionality in E-commerce website E.g. When we see a product on website and product have 2 or 3 images. When we keep pointer on image, displayed image has been changed with hovered image.

I have created two table Tb_Products (To store Products information)

Tb_ProductImage (To store the product image path)

Create a store procedure to fetch the products detail from database.

Create Proc GetProductsDetail

As begin

Select tbp.ProductName,tbp.ProductDescription,tbp.Price,img.ProductImagePath from dbo.Tb_Products tbp

inner join dbo.Tb_ProductImage img on tbp.id = img.ProductID

End

Add a webform to project and design the page as code given below

HTML Markup of page:-

<table><tr><td>

    <div id="largeimage" class="divImage">

        <asp:Image ID="Img1" src="images/processing.gif" Style="padding-left: 250px; padding-top: 150px;

            display: none;" runat="server" />

        <asp:Image ID="productimage" runat="server" width="393px"/>

    </div> 

          <asp:Repeater ID="rptthumb" runat="server">

        <ItemTemplate>     

           <asp:Image ID="imgthumb" class="imgthumbnail" runat="server"  ImageUrl='<%# Eval("ProductImagePath") %>'/>

        </ItemTemplate>

        </asp:Repeater>      

   </td>

   <td>

   <table>

   <tr><td>

      <h2><asp:Label ID="lblname" runat="server"></asp:Label></h2> </td></tr>

         <tr><td>

       <asp:Label ID="lbldescription" runat="server"></asp:Label></td></tr>

         <tr><td>

       <h3><asp:Label ID="lblprice" runat="server"></asp:Label></h3></td></tr>

   </table>

   </td>

   </tr></table>

Add the styles and Jquery in Head section of page.

<script src="js/jquery-1.4.2.min.js" type="text/javascript"></script>

    <style>

        table

        {

            margin-left:100px;

            margin-top:50px;

        }

        #largeimage

        {

            padding-bottom: 10px;

        }

        .imgthumbnail

        {

            height: 100px;

            width: 93px;

        }

       </style>

<script type="text/javascript">

    $(function () {

        $("img.imgthumbnail").mouseover(function (e) {

            var imgName = $(this).attr("src").replace("-s", "");

            $(this).css({

                border: 'solid 1px black'

            });

            $("#productimage").css({

                display: 'none'

            });

            $("#Img1").css({

                display: 'block'

            });

            $("#productimage").attr('src', imgName).load(function () {

                $("#Img1").css({

                    display: 'none'

                });

                $("#productimage").css({

                    display: 'block'

                });

            });

        });

        $("img.imgthumbnail").mouseout(function (e) {

            $(this).css({

                border: 'solid 0px red'

            });

        });

    });

</script>

Add the namespace to code file.

C#:-

using System.Data;

using System.Data.SqlClient;

using System.Configuration;

VB:-

Imports System.Data

Imports System.Data.SqlClient

Imports System.Configuration

Write the below code to bind the repeater and bind the data to label and image control.

C#:-

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["connection"].ToString());

    protected void Page_Load(object sender, EventArgs e)

    {

        if (!IsPostBack)

        {

            Bindgrid();

        }

    }

    public void Bindgrid()

    {

        SqlDataAdapter adp = new SqlDataAdapter("GetProductsDetail", con);

        adp.SelectCommand.CommandType = CommandType.StoredProcedure;

       DataTable dt = new DataTable();

       adp.Fill(dt);

       if (dt.Rows.Count > 0)

       {

           productimage.ImageUrl = dt.Rows[0]["ProductImagePath"].ToString();

           lblname.Text = dt.Rows[0]["ProductName"].ToString();

           lbldescription.Text = dt.Rows[0]["ProductDescription"].ToString();

           lblprice.Text = dt.Rows[0]["Price"].ToString();

           rptthumb.DataSource = dt;

           rptthumb.DataBind();

        }

    }

VB:-

Private con As New SqlConnection(ConfigurationManager.ConnectionStrings("connection").ToString())

    Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load

        If Not IsPostBack Then

            Bindgrid()

        End If

    End Sub

    Public Sub Bindgrid()

        Dim adp As New SqlDataAdapter("GetProductsDetail", con)

        adp.SelectCommand.CommandType = CommandType.StoredProcedure

        Dim dt As New DataTable()

        adp.Fill(dt)

        If dt.Rows.Count > 0 Then

            productimage.ImageUrl = dt.Rows(0)("ProductImagePath").ToString()

            lblname.Text = dt.Rows(0)("ProductName").ToString()

            lbldescription.Text = dt.Rows(0)("ProductDescription").ToString()

            lblprice.Text = dt.Rows(0)("Price").ToString()

            rptthumb.DataSource = dt

            rptthumb.DataBind()

        End If

    End Sub
