Detailed Description

Facilitates WPF data binding to enums by providing an enumeration of Choices, read/write access to a string representation (which may be localized in derived classes), and the type-safe enum value itself.

When providing a public EnumProvider property, you need to wire up the PropertyChanged event:

public EnumProvider<MyType> MyProperty
{
    get
    {
        if (_myPropertyField == null)
        {
            _myPropertyField = new EnumProvider<MyType>(_myModel.Property);
            _myPropertyField.PropertyChanged += (sender, args) =>
            {
                _myModel.Property = _myPropertyField.AsEnum;
            };
        }
        return _myPropertyField;
    }
}

To bind to a ComboBox to an EnumProvider property, use:

<ComboBox 
    ItemsSource="{Binding MyEnumProviderProperty.Choices}"
    ToolTip="{Binding MyEnumProviderProperty.ToolTip}"
    SelectedItem="{Binding MyEnumProviderProperty.SelectedItem}"
/>

To make use of per-item enabled states and tool tips, it is helpful to define a generic style in a central resource dictionary:

<Style TargetType="{x:Type ComboBoxItem}">
    <Setter Property="Control.ToolTip" Value="{Binding Path=ToolTip, Mode=OneWay}" />
    <Setter Property="IsEnabled" Value="{Binding Path=IsEnabled, Mode=OneWay}" />
</Style>

Since generic type parameters cannot be enums, the workaround "struct, IConvertible" is used here as suggested in http://stackoverflow.com/q/79126/270712

Type Constraints

T	:	struct
T	:	IConvertible
