Use the FocusDate property to get or set the date that currently has focus. When SingleSel is True, you can use FocusDate to select a new date. Use the SingleSel property to specify whether the control supports single or multiple selection. Use the HideSelection property to determine whether the selection is hidden when the control loses focus. The control fires the FocusChanged event whenever a new date is focused. If SingleSel is False or the focused date is disabled, the control draws a focus rectangle around the date. Use the Disabled property to disable a date. Use SelDate and SelCount to retrieve or set the collection of selected dates. If focusing a new date requires browsing to a different month or year, the control fires the DateChanged event.
