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

Wenn der Kalender angezeigt wird, gehen einige Datumsangaben voran, einige folgen den Monaten, die vollständig angezeigt werden. Mithilfe der TrailingForeColor -Eigenschaft können Sie die Farbe des Texts für diese Datumsangaben ändern.

Ab Windows Vista und abhängig vom Design ändert das Festlegen dieser Eigenschaft möglicherweise nicht das Erscheinungsbild des Kalenders. Wenn windows beispielsweise auf die Verwendung des Aero-Designs festgelegt ist, hat das Festlegen dieser Eigenschaft keine Auswirkungen. Dies liegt daran, dass eine aktualisierte Version des Kalenders mit einer Darstellung gerendert wird, die zur Laufzeit aus dem aktuellen Betriebssystemdesign abgeleitet wird. Wenn Sie diese Eigenschaft verwenden und die frühere Version des Kalenders aktivieren möchten, können Sie visuelle Stile für Ihre Anwendung deaktivieren. Das Deaktivieren von visuellen Stilen kann sich auf das Aussehen und Verhalten anderer Steuerelemente in Ihrer Anwendung auswirken. Um visuelle Stile in Visual Basic zu deaktivieren, öffnen Sie den Projekt-Designer, und deaktivieren Sie das Kontrollkästchen Visuelle XP-Stile aktivieren. Um visuelle Stile in C# zu deaktivieren, öffnen Sie Program.cs, und kommentieren Sie Application.EnableVisualStyles(); aus.
