property Schedule.AllowSelectEvent as AllowKeysEnum
Specifies the combination of keys that allows the user to select events in the schedule panel.

TypeDescription
AllowKeysEnum An AllowKeysEnum expression that specifies the keys to allow the user to select events in the schedule view.
By default, the AllowSelectEvent property is exLeftClick, which means that the event gets selected as soon as the user clicks it ( using the left mouse button ). 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 LayoutStartChanging(exScheduleSelectionChange) event occurs once the user is about to change the selection ( of events ), in the schedule view. The LayoutEndChanging( exScheduleSelectionChange) event occurs once the user changed the selection ( of events ), in the schedule view. The Selectable property of the event indicates whether the event can be selected at runtime. The Selected property of the Event indicates whether the current event is selected or unselected. The SelectEventStyle property indicates the way the selected events are shown. The SelectEventColor property specifies the visual appearance of the selected event. The SelectEventTextColor property specifies the foreground color of the selected event. The AllowSelectEventRect property indicates whether the user can select multiple events by dragging a rectangle. The AllowToggleSelectKey property indicates the key to be used so the user can toggle a selected event. 

The Selection property gets or sets a safe array of selected events. The /NET or /WPF version provides the SelEvents property of List<Event> type to get or sets the new selection using a collection of Event objects.

The AllowSelectEvent property on exDisallow specifies that no selection is allowed in the schedule view, so no event can be selected. Use the Selectable property of the Event on False, to specify whether the event is selectable or not .
