A Checkbox can be thinked like a Button. You don't click it, you check it.

We recreate the previous demo. Look the code:

The Window1.xaml file is:

<Window  
    xmlns="http://schemas.microsoft.com/winfx/avalon/2005"
    xmlns:x="http://schemas.microsoft.com/winfx/xaml/2005"
    x:Class="DMU.Window1"
    Title="DMU Tutorials Serie"
    Top="100"
    Left= "100"
    Width="400"
    Height="400"
>

<Canvas  Width="400"  Height="400" Background="DeepSkyBlue"  >
  <TextBlock  Name="Text1"   Canvas.Top="50" Canvas.Left="100"   FontSize="14">Check boxes to populate list</TextBlock>
  <CheckBox   Name="Bt1" Canvas.Top="100" Canvas.Left="100" Checked = "Hat">Hat</CheckBox>
  <CheckBox  Name="Bt2" Canvas.Top="100" Canvas.Left="200" Checked = "Shoe">Shoe</CheckBox>
  <CheckBox   Name="Bt3" Canvas.Top="100" Canvas.Left="300" Checked = "Shirt">Shirt</CheckBox>
  <ListBox Name="TheLB" Canvas.Top="150" Canvas.Left="100" Width="100"   Height="55" SelectionChanged="Print"  >
	<ListBoxItem>Trousers</ListBoxItem>
  </ListBox>
  <TextBlock    Canvas.Top="250" Canvas.Left="100"   FontSize="14"  >Click one to select</TextBlock>
  <TextBox Name = "TheItem" Canvas.Top="300" Canvas.Left="100" FontSize="14"/>
 </Canvas>
</Window>

And the Window1.xaml.cs file is:

namespace DMU{
	 
public partial class Window1 : Window{
  
  public Window1(){
   InitializeComponent();
  }
 private void Hat(object sender, RoutedEventArgs e){
     ListBoxItem li = new ListBoxItem();
     li.Content =  "Hat" ;
     TheLB.Items.Add(li);
     Bt1.IsEnabled = false;
     
 }
private void Shoe(object sender, RoutedEventArgs e){
    ListBoxItem li = new ListBoxItem();
     li.Content = "Shoe" ;
     TheLB.Items.Add(li);
     Bt2.IsEnabled = false;
 }
private void Shirt(object sender, RoutedEventArgs e){
    ListBoxItem li = new ListBoxItem();
    li.Content = "Shirt";
    TheLB.Items.Add(li);
    Bt3.IsEnabled = false;
 }
    void Print(object sender, SelectionChangedEventArgs args)
    {
        ListBoxItem lboxitem = new ListBoxItem();
        lboxitem = TheLB.SelectedItem as ListBoxItem;
        
        TheItem.Text = "Selected: " + lboxitem.Content.ToString();

        

    }   
 } 
} 

IMPORTANT: We are not presenting the other 3 usual files of the application.

Pay attention how we are doing a conversion (as ListBoxItem). This works for some types.

You can run the application. Please, you need to liberate the firewall.

After this introduction, some properties:

Background

The value will be a color.

BorderBrush

Also a color.

BorderThickness

Click

If the CheckBox is checked, unchecks it; and vice-versa. Changes the property IsChecked.

Height

IsChecked

You need to use True | False. It's a read/write property.

IsEnabled

Width

Some events. To be overrided.

The more important (you can see how to use it at the sample):
