Bind a DataGridComboBoxColumn to an Enum - wpf

Question

I have a simple DataGrid which I want the user to add some rows to.
However I want one of the columns to be a ComboBox with it's values taken from an enum.
What's the simplest way of doing this in my XAML?
I've tried following but I get the error "Two-way binding requires Path or XPath"
<Window.Resources>
<ObjectDataProvider x:Key="myEnumData"
MethodName="GetValues"
ObjectType="{x:Type sys:Enum}">
<ObjectDataProvider.MethodParameters>
<x:Type TypeName="local:MyEnum" />
</ObjectDataProvider.MethodParameters>
</ObjectDataProvider>
</Window.Resources>
...
<DataGrid.Columns>
<DataGridComboBoxColumn Header="MyHeader" DisplayMemberPath="EnumValue"
SelectedItemBinding="{Binding Source={StaticResource myEnumData}}">
</DataGridComboBoxColumn>
</DataGrid.Columns>

Answer 1

You are trying to bind the selected item when you (presumably) want to bind the list of available items. Change your binding to this:
<DataGridComboBoxColumn Header="MyHeader"
ItemsSource="{Binding Source={StaticResource myEnumData}, Mode=OneWay}">
</DataGridComboBoxColumn>

XAML
xmlns:ext="clr-namespace:Project.Core.Tools;assembly=Project.Core"
<DataGridComboBoxColumn ItemsSource="{x:Static ext:Extensions.GetEnumTypes}" SelectedItemBinding="{Binding EnumType}" />
Static Class
public static IEnumerable<EnumType> GetEnumTypes => Enum.GetValues(typeof(EnumType)).Cast<EnumType>();

XAML:
<DataGridComboBoxColumn ItemsSource="{Binding Orientantion, Mode=OneTime, Converter={Converts:EnumToItemSourceConverter}}" SelectedItem="{Binding Orientantion}"/>
C#:
public enum OrientantionTypes : int { Custom, Automatic}
public OrientantionType Orientantion { get; set;}
Converter:
public class EnumToItemSourceConverter: MarkupExtension, IValueConverter
{
public override object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
if (!(value is Enum ))
return null;
{
Type enumType = value.GetType();
var listType = typeof(List<>);
var constructedListType = listType.MakeGenericType(enumType);
var instance = Activator.CreateInstance(constructedListType);
foreach (var m in Enum.GetValues(enumType))
{
((IList)instance).Add(m);
}
return (IList)instance;
}
return null;
}
public virtual object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
public override object ProvideValue(IServiceProvider serviceProvider)
{
return this;
}
}
