DateMode: CalendarDateMode;
The DateMode property determines the component look.
If the property is set to CalendarDateMode.ComboBox, the component is used to display and change the date value. The date can be changed using the drop-down calendar, or insert the value of day, month, and year manually. If the property is set to CalendarDateMode.UpDown, the component is used to display and change the time value. The time can be changed using the SpinUp and SpinDown buttons, or set the value of hour, minutes, and seconds manually.
