Programmatically change CheckBoxList enable disable property in ASP.NET

1:54 AMMonday, October 28, 2013
In previous example we have been covered public properties of CheckBoxList control such as
<%@ 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>Example of Enable disable property of CheckBoxList</title>
    <style type="text/css">
        .style1 {
            font-size: larger;
        }
    </style>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <strong><span class="style1">Example of Enable disable property of CheckBoxList</span></strong><br />
        <asp:CheckBoxList ID="CheckBoxList1" runat="server" Width="168px">
            <asp:ListItem>AdRotator Control</asp:ListItem>
            <asp:ListItem>BulletedList Control</asp:ListItem>
            <asp:ListItem>Button Control</asp:ListItem>
            <asp:ListItem>Calendar Control</asp:ListItem>
        </asp:CheckBoxList>
        <br />
        <asp:Button ID="Button1" runat="server" onclick="Enable"
            Text="Enable" Width="61px" />
    &nbsp;<asp:Button ID="Button2" runat="server" onclick="Disable"
            Text="Disable" Width="61px" />
    </div>
    </form>
</body>

</html>

Codebehind
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

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

    }
  
    protected void Disable(object sender, EventArgs e)
    {
        CheckBoxList1.Enabled = false;
    }
    protected void Enable(object sender, EventArgs e)
    {
        CheckBoxList1.Enabled = true;
    }
}

Output
