CalendarDay.IsSelectable Property

Gets or sets a value that indicates whether the date represented by an instance of this class can be selected in the Calendar control.

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

public bool IsSelectable { get; set; }

Property Value

Type: System.Boolean
true if the date can be selected; otherwise, false.

Use the IsSelectable property to specify or determine whether the date represented by an instance of this class can be selected in the Calendar control. This allows you to programmatically control the appearance behavior of the day, based on this value.

The following example demonstrates how to use the IsSelectable property to disable the ability to select the current date on the Calendar control. Note that the Day property of the DayRenderEventArgs object passed into the DayRender event handler is the CalendarDay object.
