Assembly: System.Web (in System.Web.dll)

Syntax

[AspNetHostingPermissionAttribute(SecurityAction.LinkDemand, Level = AspNetHostingPermissionLevel.Minimal)]
public class CalendarDay

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.

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. 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.
