[WPF] Displaying Enum Values using Data Binding

--> DataBinding 到enum valuem, Copy & Paste如下

Some of the FAQs about data binding are:

• How do I bind to a method?

• How do I bind between instantiated controls?

• How do I bind an ItemsControl to an enum?

I put together a quick sample that should answer the above questions:

<Window

  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

  xmlns:x="http://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>

The ListBox and the Button are hooked up such that you can “control”

the HorizontalAlignment value of the Button by selecting a value in the

ListBox.
