Property Value

Type: System::Boolean
true if today's date is identified with a circle or a square; otherwise, false. The default is true.

The following code example displays a form containing a MonthCalendar control that displays one calendar year. The example demonstrates setting the BackColor, ForeColor, TitleBackColor, TitleForeColor, CalendarDimensions, and TrailingForeColor properties to customize the look of the calendar control. Other properties such as AnnuallyBoldedDates, BoldedDates, and MonthlyBoldedDates are set to customize which dates are bold. The example also sets the FirstDayOfWeek, MaxDate, MinDate, and MaxSelectionCount properties to change the calendar format. The DateSelected and DateChanged events are also handled and their status is displayed on the form.
