MaxAlternateSelectedDays プロパティ

UltraScheduleControlBase.UseAlternateSelectedDateRanges プロパティが True に設定されている UltraScheduleControlBase 派生コントロールにおいて、一度に選択可能な最大の日数を取得または設定します。
シンタックス
public int MaxAlternateSelectedDays {get; set;}
解説

AlternateSelectTypeDay プロパティの値によっては、実際に選択できる Day オブジェクトの数が少なくなる場合があります。たとえば、AlternateSelectTypeDayが SelectTypeSingle に設定されると、一度に選択できるのは 1 日のみになります。

BeforeAlternateSelectedDateRangeChange イベントが処理中の間、このプロパティは変更できません。
