The SelectDate property can be used to programmatically select or unselect the giving date. An alternative to SelectDate is using the Selection that can uses an expression to indicate the dates to be selected. The Selection = "0" unselects all dates in the calendar panel. The Select method can be used to select by code the current month, current week, current week day and the current/focus day.

The SelCount property counts the dates being selected in the calendar panel. The SingleSel property indicates whether the user can select one or multiple dates. If the SingleSel property is True, the SelCount property always returns 1. The SelDate property can be used to get the selected date giving its index in the selection dates collection. The AllowSelectDate property indicates the keys combination so the user can select new dates in the calendar panel, and so, new dates to be shown in the schedule view. Once the user starts selecting a new date in the calendar panel, the control fires the LayoutStartChanging(exCalendarSelectionChange). Once a new date is selected, the LayoutEndChanging(exCalendarSelectionChange) event occurs. The DateFromPoint property indicates the date in the calendar panel from the cursor.

The following samples shows how programmatically you can select a single date:
