例
次の例では、オブジェクトのプロパティを使用して、 CalendarDay イベントに表示されている日付が、表示される月であるか、 DayRender または土曜日でも日曜日でもないかどうかを判断する方法を示します。The following example demonstrates how to use the properties of a CalendarDay object to determine whether the date being rendered in the DayRender event is in the displayed month and are not either a Saturday or a Sunday. これらの日付は黄色で表示されます。These dates are displayed in yellow. Day DayRenderEventArgs イベントハンドラーに渡されるオブジェクトのプロパティ DayRender がオブジェクトであることに注意して CalendarDay ください。Note that the Day property of the DayRenderEventArgs object passed into the DayRender event handler is the CalendarDay object.

IsWeekendこのクラスのインスタンスで表される日付が土曜日または日曜日のどちらであるかをプログラムで判断するには、プロパティを使用します。Use the IsWeekend property to programmatically determine whether the date represented by an instance of this class is either a Saturday or a Sunday. これにより、この値に基づいて、日付の外観または動作をプログラムによって制御できます。This allows you to programmatically control the appearance or behavior of the day, based on this value.
