Introduction:
In this article I will explain how to bind images to dropdownlist in asp.net using JQuery.
If you observe above code I am binding title to dropdownlist elements by using BindTitles() method. Here our JQuery plugin will take the title of dropdownlist elements and display the images beside of the text.
In this article I will explain how to bind images to dropdownlist in asp.net using JQuery.
Description:
In previous articles I explained about how to implement cascading dropdownlist and Ajax Cascading dropdownlist. Now I will explain how to bind dropdownlist with images dynamically in asp.net using JQuery. In one of website I saw one dropdownlist that contains Country names along with country flags. I feel it’s better to write post to explain how to bind images to dropdownlist in asp.net. To implement this concept by using JQuery plugin we can achieve this easily.

I feel it’s better to write post to explain how to bind images to dropdownlist in asp.net. To implement this concept by using JQuery plugin we can achieve this easily.
To implement concept first design table in your database and enter data as shown below
Column Name | Data Type | Allow Nulls |
ID | int(set identity property=true) | No |
CountryName | varchar(50) | Yes |
CountryImage | varchar(50) | Yes |
After completion of table creation enter data in table like as show in below.
 |
Here I am getting images data from already inserted data if you want to dynamically insert images in database check this post insert images in folder and images path in database.
Now open Visual Studio and create new website after that right click on your website and add new folder and give name as Images and insert country flag image in that folder you should get it from attached folder.After that write the following code in your aspx page
<html xmlns="http://www.w3.org/1999/xhtml"> <head id="Head1" runat="server"> <title>Dropdownlist with Images</title> <link rel="stylesheet" type="text/css" href="msdropdown/dd.css" /> <script type="text/javascript" src="msdropdown/js/jquery-1.6.1.min.js"></script> <script type="text/javascript" src="msdropdown/js/jquery.dd.js"></script> <!-- Script is used to call the JQuery for dropdown --> <script type="text/javascript" language="javascript"> $(document).ready(function(e) { try { $("#ddlCountry").msDropDown(); } catch (e) { alert(e.message); } }); </script> </head> <body> <form id="form1" runat="server"> <table> <tr> <td align="right"> <b>Country:</b> </td> <td> <asp:DropDownList ID="ddlCountry" runat="server" Width="150px" onselectedindexchanged="ddlCountry_SelectedIndexChanged" AutoPostBack="true"></asp:DropDownList> </td> </tr> <tr> <td> <b>Seelcted Country:</b> </td> <td> <asp:Label ID="lbltext" runat="server"></asp:Label> </td> </tr> </table> </form> </body> </html> |
If you observe above code in header section I added some of script files and css file by using those files we have a chance to add images in dropdownlist. To get those files download attached sample code and use it in your application.
After completion of aspx page design add following namespaces in code behind
C#.NET Code
using System; using System.Data; using System.Data.SqlClient; using System.Web.UI.WebControls; |
After add namespace write the following code
protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { BindDropDownList(); BindTitles(); lbltext.Text = ddlCountry.Items[0].Text; } } /// <summary> /// This Method is used to bind titles to each element of dropdown /// </summary> protected void BindTitles() { if (ddlCountry != null) { foreach (ListItem li in ddlCountry.Items) { li.Attributes["title"] = "Images/" + li.Value; // setting text value of item as tooltip } } } /// <summary> /// Bind Dropdownlist Data /// </summary> protected void BindDropDownList() { SqlConnection con = new SqlConnection("Data Source=SureshDasari;Initial Catalog=MySampleDB;Integrated Security=true"); con.Open(); SqlCommand cmd = new SqlCommand("select * from CountryImages", con); SqlDataAdapter da = new SqlDataAdapter(cmd); DataSet ds = new DataSet(); da.Fill(ds); ddlCountry.DataTextField = "CountryName"; ddlCountry.DataValueField = "CountryImage"; ddlCountry.DataSource = ds; ddlCountry.DataBind(); con.Close(); } protected void ddlCountry_SelectedIndexChanged(object sender, EventArgs e) { lbltext.Text = ddlCountry.SelectedItem.Text; BindTitles(); } |
VB.NET Code
Imports System.Data Imports System.Data.SqlClient Imports System.Web.UI.WebControls Partial Class VbSample Inherits System.Web.UI.Page Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load If Not IsPostBack Then BindDropDownList() BindTitles() lbltext.Text = ddlCountry.Items(0).Text End If End Sub ''' <summary> ''' This Method is used to bind titles to each element of dropdown ''' </summary> Protected Sub BindTitles() If ddlCountry IsNot Nothing Then For Each li As ListItem In ddlCountry.Items ' setting text value of item as tooltip li.Attributes("title") = "Images/" & li.Value Next End If End Sub ''' <summary> ''' Bind Dropdownlist Data ''' </summary> Protected Sub BindDropDownList() Dim con As New SqlConnection("Data Source=SureshDasari;Initial Catalog=MySampleDB;Integrated Security=true") con.Open() Dim cmd As New SqlCommand("select * from CountryImages", con) Dim da As New SqlDataAdapter(cmd) Dim ds As New DataSet() da.Fill(ds) ddlCountry.DataTextField = "CountryName" ddlCountry.DataValueField = "CountryImage" ddlCountry.DataSource = ds ddlCountry.DataBind() con.Close() End Sub Protected Sub ddlCountry_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) lbltext.Text = ddlCountry.SelectedItem.Text BindTitles() End Sub End Class |
Now run your application and check how your dropdownlist will be
