How to: Bind to an Enumeration

This example shows how to bind to an enumeration by binding to the enumeration's GetValues method.

Example

In the following example, the ListBox displays the list of HorizontalAlignment enumeration values through data binding. The ListBox and the Button are bound such that you can change the HorizontalAlignment property value of the Button by selecting a value in the ListBox.

<Window
  xmlns="https://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="https://schemas.microsoft.com/winfx/2006/xaml"
  xmlns:sys="clr-namespace:System;assembly=mscorlib" 
  SizeToContent="WidthAndHeight" 
  Title="Show Enums in a ListBox using Binding">

  <Window.Resources>
    <ObjectDataProvider MethodName="GetValues"
                        ObjectType="{x:Type sys:Enum}"
                        x:Key="AlignmentValues">
      <ObjectDataProvider.MethodParameters>
        <x:Type TypeName="HorizontalAlignment" />
      </ObjectDataProvider.MethodParameters>
    </ObjectDataProvider>
  </Window.Resources>

  <Border Margin="10" BorderBrush="Aqua"
          BorderThickness="3" Padding="8">
    <StackPanel Width="300">
      <TextBlock>Choose the HorizontalAlignment value of the Button:</TextBlock>
      <ListBox Name="myComboBox" SelectedIndex="0" Margin="8"
               ItemsSource="{Binding Source={StaticResource AlignmentValues}}"/>
      <Button Content="Click Me!"
              HorizontalAlignment="{Binding ElementName=myComboBox,
                                            Path=SelectedItem}"/>
    </StackPanel>
  </Border>
</Window>
