CalendarDay.IsOtherMonth Property

 

Gets a value that indicates whether the date represented by an instance of this class is in a month other than the month displayed in the Calendar control. This property is read-only.

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

public bool IsOtherMonth { get; }

Property Value

Type: System.Boolean

true if the date represented by an instance of this class is in a month other than the month displayed in the Calendar control; otherwise, false.

Use the IsOtherMonth property to programmatically determine whether the date represented by an instance of this class is in a month other than the month displayed in the Calendar control. 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.
