CalendarDay.IsToday Property

Gets a value that indicates whether the date represented by an instance of this class is the same date specified by the TodaysDate property of the Calendar control. This property is read-only.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

public bool IsToday { get; }
/** @property */
public boolean get_IsToday ()

public function get IsToday () : boolean

Property Value

true if the date represented by an instance of this class is the same date specified by the TodaysDate property of the Calendar control; otherwise, false.

Use the IsToday property to programmatically determine whether the date represented by an instance of this class is the same date specified by the TodaysDate property of the Calendar control. This allows you to programmatically control the appearance or behavior of the day, based on this value.

NoteNote

Although the date specified by the TodaysDate property is usually the system date on the server, it is possible to change it, if necessary.

The following example demonstrates how to use the IsToday property to determine if the date being rendered in the DayRender event is the current date. If the date is the current date, it is displayed in a yellow cell with red text on the Calendar. Note that the Day property of the DayRenderEventArgs object passed into the DayRender event handler is the CalendarDay object.
