By default, the AllowToggleSchedule property is exLeftClick + exDblClick, which means a double click will toggle the schedule view. The AllowEditEvent property uses the same keys combination as AllowToggleSchedule property, so if you double click an event, the inline editing is performed, else if clicking outside of the event the toggling the schedule view is performed. By toggling the schedule view we mean that for instance, if you select the entire month to be viewed, a double click on a date will bring the date to be shown on the schedule view, and the next double click will restore the month view. You can specify an event being not editable, using the Editable property on exNoEditable, or you can set the AllowEditEvent property on exDisallow, to prevent editing any of the schedule's events.
