The following code explains you how to create a DropDownList control that contains five items.
Code for Default.aspx:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<script runat="server">
Sub SelectedItem_Change(ByVal sender As Object, ByVal e As EventArgs)
' Here we set the background color for days in the calender control based on the selected value in the DropDownList control.
Calendar1.DayStyle.BackColor = _
System.Drawing.Color.FromName(ColorList.SelectedItem.Value)
End Sub
</script>
<body>
<form id="Form1" runat="server">
<h3>

</tr>
<tr>
<td>
