Beispiel

Im folgenden Codebeispiel wird das Initialisieren eines DateTimePicker-Steuerelements durch Festlegen der DropDownAlign-Eigenschaft, der Value-Eigenschaft, der Format-Eigenschaft und der CustomFormat-Eigenschaft veranschaulicht. Zum Ausführen dieses Beispiels fügen Sie den folgenden Code in ein Formular ein und rufen den InitializeDateTimePicker im Konstruktor oder in Load-Ereignisbehandlungsmethode des Formulars auf.
