この型の public static (Visual Basicでは Shared) のすべてのメンバは、マルチスレッド操作で安全に使用できます。インスタンスのメンバの場合は、スレッドセーフであるとは限りません。
解説
現在選択されている日付や日付範囲が変化すると、 DateChanged イベントが発生します。たとえば、選択されている日付をユーザーが現在の月の中で明示的に変更した場合や、翌月または前月に移動したことによって選択されている日付が変わってしまう場合に、このイベントが発生します。選択されている日付をユーザーが明示的に変更すると、 DateSelected イベントが発生します。 DateRangeEventArgs コンストラクタは、新しく選択された日付範囲の開始日と終了日を指定します。
イベント処理の詳細については、「 イベントの利用 」を参照してください。
使用例
[Visual Basic, C#, C++] 1 暦年を表示する MonthCalendar コントロールが配置されたフォームを表示する例を次に示します。この例では、 BackColor 、 ForeColor 、 TitleBackColor 、 TitleForeColor 、 CalendarDimensions 、および TrailingForeColor などの各プロパティを設定して月間予定表コントロールの外観をカスタマイズしています。 AnnuallyBoldedDates 、 BoldedDates 、および MonthlyBoldedDates など、その他のプロパティは、どの日付を太字にするかをカスタマイズするために設定されます。この例では、 FirstDayOfWeek 、 MaxDate 、 MinDate 、および MaxSelectionCount を含め、暦の書式を変更するプロパティも設定します。 DateSelected イベントおよび DateChanged イベントも処理され、ステータスがフォームに表示されます。
