I would like to visualize the scheduling area without the horizontal lines of the timeslots so you see for each owner/date a colored rectangle.
Is there a possibility to hide this lines of each TimeSlot?
You could set the BackColor property of the control's WorkingHourTimeSlotAppearance/NonWorkingHourTimeSlotAppearance to Color.Transparent. This will allow the TimeSlotUIElements to exist, but they will be completely transparent.
