Below is code for .aspx file

XML

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Untitled Page</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    <asp:DropDownList runat="server" ID="DropDownList1" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged" AutoPostBack="true" >
    <asp:ListItem>--SELECT--</asp:ListItem>
    <asp:ListItem>Ford</asp:ListItem>
    <asp:ListItem>Maruti</asp:ListItem>
    <asp:ListItem>BMW</asp:ListItem>
    </asp:DropDownList>

    <asp:Label ID="Label1" runat="server" Visible="false"></asp:Label>
    </div>
    </form>
</body>
</html>

Now put following in .cs file in "DropDownList1_SelectedIndexChanged" Event

C#

using System;

using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class Default2 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
    {
        if (DropDownList1.SelectedIndex > 0)
        {
            Label1.Text = DropDownList1.SelectedItem.Text;
            Label1.Visible = true;
        }
