Change BackColor of CheckBox dynamically in ASP.NET

October 03, 2013 0 Comments

If you want to change back-color of the checkbox programmatically then you should use back-color  property at codebehind.
lets take a simple example for completing the task. Take a webform control and place one checkBox and one button control onto the design window. Now at time we can handle onClick event.
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default4.aspx.cs" Inherits="Default4" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">

<html xmlns="">
<head runat="server">
    <form id="form1" runat="server">
        <asp:CheckBox ID="CheckBox1" runat="server"
            Text="CheckBox for multiple selection" />
        <br />
        <br />
        <asp:Button ID="Button1" runat="server" onclick="Button1_Click"
            Text="Change back color" />

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

public partial class Default4 : System.Web.UI.Page
    protected void Page_Load(object sender, EventArgs e)

    protected void Button1_Click(object sender, EventArgs e)
        CheckBox1.BackColor = System.Drawing.Color.Green;
