Namespace: System.Web.UI.WebControls

public function get IsWeekend () : boolean

Not applicable.

Property Value

true if the date represented by an instance of this class is either a Saturday or a Sunday; otherwise, false.

Use the IsWeekend property to programmatically determine whether the date represented by an instance of this class is either a Saturday or a Sunday. This allows you to programmatically control the appearance or behavior of the day, based on this value.

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 are not either a Saturday or a Sunday. These dates are displayed in yellow. Note that the Day property of the DayRenderEventArgs object passed into the DayRender event handler is the CalendarDay object.
