Use the VisibleDate property to programmatically set the month to display on the Calendar control. The specified date can be any date in the month you want to display, although it is common to use the first date in the month. This property is set using a System.DateTime object.
The VisibleDate property is updated before the VisibleMonthChanged event is raised. You can provide a custom OnVisibleMonthChanged event handler to set the VisibleDate property and override the automatically generated value.
