This request is to add Working hours range of the view, which will style the cells as working and non working. In addition, add a property ShowWorkingHours while will determine whether non-working hours are visible or not. Or perhaps for the sake of consistency, we can have API as in the day view: dayView.RangeFactor = ScaleRange.QuarterHour dayView.RulerStartScale = 9 dayView.RulerStartScaleMinutes = 30 dayView.RulerEndScale = 14 dayView.RulerEndScaleMinutes = 45
