Beispiele
Im folgenden Codebeispiel wird ein Formular mit einem MonthCalendar Steuerelement angezeigt, das ein Kalenderjahr anzeigt. Das Beispiel veranschaulicht das Festlegen der BackColorEigenschaften , ForeColor, TitleBackColor, TitleForeColor, CalendarDimensionsund TrailingForeColor zum Anpassen des Erscheinungsbilds des Kalendersteuerelements. Andere Eigenschaften wie AnnuallyBoldedDates, BoldedDatesund MonthlyBoldedDates werden festgelegt, um anzupassen, welche Datumsangaben fett formatiert sind. Im Beispiel werden auch die FirstDayOfWeekEigenschaften , MaxDate, MinDateund MaxSelectionCount festgelegt, um das Kalenderformat zu ändern. Die DateSelected Ereignisse und DateChanged werden ebenfalls behandelt, und ihre status wird im Formular angezeigt.

Hinweise
Die Bildlaufrate ist die Anzahl der Monate, in denen das Steuerelement seine Anzeige verschiebt, wenn der Benutzer auf einen Bildlaufpfeil klickt. Wenn dieser Wert 0 ist, wird die Anzahl der Monate auf den Standardwert zurückgesetzt, d. h. die Anzahl der Monate, die im Steuerelement angezeigt werden. Der maximale Wert ist 20.000.
