IsSelected Property

CalendarDay.IsSelected Property

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

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

public bool IsSelected { get; }
/** @property */
public boolean get_IsSelected ()

public function get IsSelected () : boolean

Property Value

true if the date represented by an instance of this class is selected in the Calendar control; otherwise, false.

Use the IsSelected property to programmatically determine whether the date represented by an instance of this class is selected 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 IsSelected property to determine if the current date is selected in the Calendar. Note that the Day property of the DayRenderEventArgs object passed into the DayRender event handler is the CalendarDay object.
