Answer 1

A slightly modified answer for what David Ward has proposed. Here is the full code

Add a value converter to resouces like this

Then define following xaml

The value converter looks like this

[ValueConversion(typeof(bool), typeof(bool))]
  public class NegateConverter : IValueConverter
  {
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
     return  !((bool)value);
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
      throw new NotImplementedException();
    }
  }
