WPF CheckBox Control (C#)

CheckBox enables the user to select whether an option is on or off.

XAML:

<Window x:Class="WpfApplication1.MainWindow"

        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <CheckBox Content="CheckBox" Height="16" HorizontalAlignment="Left" Margin="10,10,0,0" Name="checkBox1" VerticalAlignment="Top" Checked="checkBox1_Checked" Unchecked="checkBox1_Unchecked" />
        <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="12,32,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" />
    </Grid>
</Window>

C# code behind:

 private void checkBox1_Checked(object sender, RoutedEventArgs e)

        {
                MessageBox.Show("checkBox1 Checked");
        }
        private void checkBox1_Unchecked(object sender, RoutedEventArgs e)
        {
              MessageBox.Show("checkBox1 UnChecked");
        }
        private void button1_Click(object sender, RoutedEventArgs e)
        {
            if (checkBox1.IsChecked == true)
                MessageBox.Show("checkBox1 Checked");
            else
                MessageBox.Show("checkBox1 UnChecked");
        }
