I have a XamDataGrid with a XamComboEditor set as one of the fields, the item-source for this field is a list of objects with a enum as the id and a string as the name.

When the XamDataGrid is gruoped by this field it displays the id as the fieldname instead of the name.

What's really weird is that if I reload the item-source the name is displayed correctly.

<igDP:ComboBoxField Name="field" Label="fieldLabel" Width="200" DisplayMemberPath="Name" ValuePath="Id" DropDownButtonDisplayMode="OnlyInEditMode">
	<igDP:ComboBoxField.EditorStyle>
		<Style TargetType="{x:Type igEditors:XamComboEditor}" BasedOn="{StaticResource XamComboEditorStyle}">
			<Setter Property="ItemsSource" Value="{Binding Path=DataContext.SelectableValues, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}" />
		</Style>
	</igDP:ComboBoxField.EditorStyle>
</igDP:ComboBoxField>

public List<SelectableValuesViewModel> SelectableValues
        { get; set; }


public class SelectableValuesViewModel
	{
		public EnumType Id
		{ get; set; }

		public string Name
		{ get; set; }

		public SelectableValuesViewModel(EnumType id, string name)
		{
			this.Id = id;
			this.Name = name;
		}
	}
