'Declaration Public Property AlternateSelectTypeDay As SelectType
public SelectType AlternateSelectTypeDay {get; set;}
The AlternateSelectTypeDay property determines how Day objects may be selected via code and through the UltraSchedule controls that are attached to the UltraCalendarInfo component and whose whose UseAlternateSelectedDateRanges property is set to true.
The property cannot be changed during the BeforeAlternateSelectedDateRangeChange event.
