NonEmptyStringToVisibleConverter.Convert Method

Convert non-null non-empty string to Visibility.Visible and any other value to Visibility.Collapsed (or Visibility.Hidden if parameter contains "Hidden").

If the parameter contains "Not", "!", or "Invert", the string evaluation result is inverted before converting to Visibility.
