Examples

The following example demonstrates how to use the properties of a CalendarDay object to determine whether the date being rendered in the DayRender event is in the displayed month and do not fall on Saturday or Sunday.

Remarks

A CalendarDay object represents a date in the Calendar control. You can use this class in the DayRender event handler to programmatically access the properties of a date as it is rendered on the Calendar control. This allows you to determine the properties of the day (such as whether the date is selectable, selected, today's date, or a weekend date) and programmatically control the appearance or behavior of the day.

For a list of initial property values for an instance of CalendarDay, see the CalendarDay constructor.
