The Preview Tab of the Schedule Control (from a ScheduleWorX View configuration) Runtime (Calendar View) properties is the primary calendar display for your users. It displays the Calendar for all possible time periods. You can't configure or create new events in this view, which makes it safe to display for any user viewing the calendar on their monitor. Scheduled events, exceptions, and holidays all appear on this view. The Preview view is shown below in the weekly view.
