'Declaration Public Property UseLegalNumberFormat As Nullable(Of Boolean)
public Nullable<bool> UseLegalNumberFormat {get; set;}
UseLegalNumberFormat is used to display list item numbers in legal format, which is essentially item numbers from ancestor levels and current level combined using '.' separator. Legal number format is achieved by setting the LevelText to "1.2.3...n." where 'n' is the level number of the level definition where legal format is desired. Without setting UseLegalNumberFormat, this value of LevelText results in item numbers from ancestor levels and current level combined using '.' separator, including any formatting that the ancestor levels may have applied to their item numbers. So if an ancestor level had its own number formatting applied, then that formatted value would be used for that level. Setting UseLegalNumberFormat to true results in the number formatting to be ignored at all levels in the replacement LevelText value.
