How to Bind an Enum to a WPF ComboBox?

Enum to ComboBox Binding in WPF

Question

An attempt to display enum values as items in a ComboBox without additional display strings has proven unsuccessful. The XAML code employs binding to a class property, but the enum values do not appear.

Answer

Binding Via Code

In the Window Loaded event handler, populate the ItemsSource property with enum values:

yourComboBox.ItemsSource = Enum.GetValues(typeof(EffectStyle)).Cast<EffectStyle>();

Binding in XAML

Utilizing ObjectDataProvider:

<Window.Resources>
    <ObjectDataProvider x:Key="dataFromEnum" MethodName="GetValues"
                        ObjectType="{x:Type System:Enum}">
        <ObjectDataProvider.MethodParameters>
            <x:Type TypeName="StyleAlias:EffectStyle"/>
        </ObjectDataProvider.MethodParameters>
    </ObjectDataProvider>
</Window.Resources>

<Grid>
    <ComboBox ItemsSource="{Binding Source={StaticResource dataFromEnum}}"
              SelectedItem="{Binding Path=CurrentEffectStyle}" />
</Grid>

Namespace Mapping

Note the usage of aliases for namespaces:

xmlns:System="clr-namespace:System;assembly=mscorlib"
xmlns:StyleAlias="clr-namespace:Motion.VideoEffects"

For proper mapping of namespaces and assemblies, refer to the MSDN documentation.
