ASP.Net: Bind Dropdownlist with Images | Neha Sharma



Introduction:

This article explains how to bind images with text in dropdownlist from your table.

Requirement:

1.       A table like below:

Table design:

Table data:


Code.aspx :

I have taken a DropdownList control to bind data from table ddl_image .Before the design you need some files like ddl.css, jquery-1.6.1.min.js and jquery.dd.js.you can download it from here.
Add these code in  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="dropdown/ddl.css" />
<script type="text/javascript" src="dropdown/js/jquery-1.6.1.min.js"></script>
<script type="text/javascript" src="dropdown/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 {
            $("#ddlprofile").msDropDown();
        } catch (e) {
            alert(e.message);
        }
    });
</script>
</head>
<body>
<form id="form1" runat="server">
<table>
<tr>
<td align="right">
<b>Profile:</b>
</td>
<td>
<asp:DropDownList ID="ddlprofile" runat="server" Width="150px" onselectedindexchanged="ddlCountry_SelectedIndexChanged" AutoPostBack="true"></asp:DropDownList>
</td>
</tr>
</table>
</form>
</body>
</html>

Code.cs :

Here I tried to addd a dropdownlist first then bind titles and then call both functions on pageload like below :

1.       Bind dropdownlist :

protected void Bindddl()
    {
        SqlConnection con = new SqlConnection("Data Source=nehashama;Initial Catalog=rp;Integrated Security=true");
        con.Open();
        SqlCommand cmd = new SqlCommand("select * from ddl_image", con);
        SqlDataAdapter adp = new SqlDataAdapter(cmd);
        DataSet ds = new DataSet();
        adp.Fill(ds);
        ddlprofile.DataTextField = "Name";
        ddlprofile.DataValueField = "Profile_image";
        ddlprofile.DataSource = ds;
        ddlprofile.DataBind();
        con.Close();
    }

2.       Bind Title :

protected void BindTitle()
    {
        if (ddlprofile != null)
        {
            foreach (ListItem li in ddlprofile.Items)
            {
                li.Attributes["title"] = "ddl/" + li.Value; // it ll set the value of items in dropdownlist as tooltip
         
            }
        }
    }

3.       Call on Page Load :

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            Bindddl();
            BindTitle();
           
        }
    }

Now save all and view the page in browser it ll work fine an DropDownList look like below image:


Thanks.
