You can use a DataTrigger, but would be more maintainable if you used a Converter. Here's a sample that uses a DataTrigger for a view of the image and text by itself, and then the same DataTrigger to display the image and text in ListBox and ComboBox, and finally, a ListBox and ComboBox that use a Converter to display the image and text:

        public EnumToImage()

        }

        private int i = 1;
        private void OnImageMouseUp( object sender, MouseButtonEventArgs e )
        {
            i++;
            Model.ImageEnum = ( Decade )i;

            if( i == 6 )
                i = 0;
        }
    }

    public enum Decade

        Ninties = 1,
        Eighties = 2,

        Sixties = 4,

                RaisePropertyChanged( "ImageEnum" );

    }

    public class DecadeEnumImageConverter : IValueConverter

        public object Convert( object value, Type targetType, object parameter, CultureInfo culture )
        {

            var myEnum = ( Decade )Enum.Parse( typeof( Decade ), value.ToString() );

                case Decade.Forties:
                    return "/EnumToImage/images/40s.jpg";
                default:
                    throw new ArgumentOutOfRangeException();
            }
        }

        public object ConvertBack( object value, Type targetType, object parameter, CultureInfo culture )
