By default, the AllowSelectCreateEvent property is exSelectCreateEventNone, which means that nothing happen if the user creates a new event. The AllowSelectCreateEvent property specifies whether the newly created event gets selected or highlighted. Use the ShowAllDayHeader property to show the schedule's All-Day header so all All-Day evens are shown on this header. The AllowCreateAllDayEvent property has effect only when the schedule displays no time scale. The AllDayEvent property indicates an all-day event. You can use the AllowSelectEvent property to change the key to allow the user select new events or you can prevent selecting any event using exDisallow value. The SelectEventColor / SelectEventTextColor indicates the background / foreground colors to be applied on the event's body when the control just highlights the event being created.
