How to bind an enum to a combobox control in WPF?

I am trying to find a simple example where the enums are shown as is. All examples I have seen tries to add nice looking display strings but I don't want that complexity.

Basically I have a class that holds all the properties that I bind, by first setting the DataContext to this class, and then specifying the binding like this in the xaml file:

<ComboBox ItemsSource="{Binding Path=EffectStyle}"/>

But this doesn't show the enum values in the
as items.

You can do it from code by placing the following code in Window Loaded event handler, for example:

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

If you need to bind it in XAML you need to use ObjectDataProvider to create object available as binding source:

<Window x:Class="YourNamespace.MainWindow"
        <ObjectDataProvider x:Key="dataFromEnum" MethodName="GetValues"
                            ObjectType="{x:Type System:Enum}">
                <x:Type TypeName="StyleAlias:EffectStyle"/>
        <ComboBox ItemsSource="{Binding Source={StaticResource dataFromEnum}}"
                  SelectedItem="{Binding Path=CurrentEffectStyle}" />
