WPF: A simple checkbox

This entry is part 13 of 54 in the series Learn WPF

This simple example shows how to create Checkbox controls and add event handlers.

When a user clicks the Checkbox the text of the control changes. The Checkbox is created using XAML.

<Window x:Class="CheckBox1.MainWindow"
        Title="MainWindow" Height="350" Width="525">
        <CheckBox Margin="50, 50, 50, 50" Name="cb1" FontSize="24" Checked="HandleChange">Check Box</CheckBox>
using System.Windows;
using System.Windows.Controls;

namespace CheckBox1
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
        public MainWindow()
        private void HandleChange(object sender, RoutedEventArgs e)
            cb1.Content = "You clicked the check box";

We need to look at the click event handler HandleChange.  Once the checkbox is clicked, the text or content in the checkbox will be updated.

Here is the output:
