Public Property ShowLeadingAndTrailingDates As Boolean
public bool ShowLeadingAndTrailingDates {get; set;}
解説

先頭日と後続日はグループで表示されますが、そのグループは特定のグループには属していません。例えば、デフォルトの日曜日の開始日を持つ 2008 年 8 月を表示するグレゴリオ暦を表示するときに、カレンダーが 7 月 27 日から 7 月 31 日までの先頭日および 9 月 1 日 から 9 月 6 日 までの後続日を表示できます。デフォルトで先頭日と後続日はコントロールの最初および最後の CalendarItemGroup で表示されます。

注: XamMonthCalendar のデフォルト テンプレートは、最初および最後の CalendarItemGroup インスタンスの ShowTrailingDates および ShowLeadingDates 値がこのプロパティに基づいて初期化されることを確認する CalendarItemGroupPanel を使用します。直接的に CalendarItemGroup インスタンスを含むためにコントロールを再テンプレートする場合、このプロパティを使用するグループを制御する必要があります。
