Hello Readers and Friends! I am happy to share some of my codes and applications. Today, I am discussing about some of the basic things in C# programming that is Checkbox Control in Windows application.

Step 1: Open Visual Studio (any version you have installed). I have VS2012,



Step 2: Select Windows form application and enter the name of application, then click OK.



Step 3: Design your windows application, like drag and drop the checkbox, buttons and labels, as per your requirement.



Step 4: The source code of my program is given below.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace Checkbox_Apps
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void checkBox1_CheckedChanged(object sender, EventArgs e)
        {
            checkBox1.ThreeState = true;
        }

        private void label1_Click(object sender, EventArgs e)
        {



        }

        private void checkBox2_CheckedChanged(object sender, EventArgs e)
        {
            checkBox2.ThreeState = true;

        }

        private void checkBox3_CheckedChanged(object sender, EventArgs e)
        {
            checkBox3.ThreeState = true;

        }

        private void checkBox4_CheckedChanged(object sender, EventArgs e)
        {
            checkBox4.ThreeState = true;

        }

        private void button1_Click(object sender, EventArgs e)
        {
            //string messagebox = "";
            if (checkBox1.Checked == true)
            {
                MessageBox.Show("Welcome to Visual Studio DownLoad Page Click Visit");
                System.Diagnostics.Process.Start("www.visualstudio.com");
            }
            if (checkBox2.Checked == true)
            {
                MessageBox.Show("Welcome to Dev C DownLoad Page Click Visit");
                System.Diagnostics.Process.Start("www.krishnasinghprogramming.blogspot.com");
            }
            if (checkBox3.Checked == true)
            {
                MessageBox.Show("Welcome to IT PROGRAMMING WORLD Page Click Visit");
                System.Diagnostics.Process.Start("www.krishnasinghprogramming.blogspot.com");
            }
            if (checkBox4.Checked == true)
            {
                MessageBox.Show("Welcome to CSHARPCORNER Page Click Visit");
                System.Diagnostics.Process.Start("www.csharpcorner.com");
            }
        }

        private void button2_Click(object sender, EventArgs e)
        {
            checkBox1.Checked = false;
            checkBox2.Checked = false;
            checkBox3.Checked = false;
            checkBox4.Checked = false;

            {
            }

        }

        private void label2_Click(object sender, EventArgs e)
        {
            label2.Text = DateTime.Now.ToShortTimeString();
        }
    }
}
