'Declaration Public Property ShowCalendarCloseButton As Nullable(Of Boolean)
public Nullable<bool> ShowCalendarCloseButton {get; set;}
This property determines whether the close button is displayed within the Infragistics.Controls.Schedules.Primitives.CalendarHeader. By default this property is set to null and the property value used is resolved based on the AllowCalendarClosing. If that property is set to false then the close button will be hidden. Otherwise it is up to the control as to whether it will display the button. XamScheduleView, for example, will not display the button by default.
Note: The enabled state is based upon the AllowCalendarClosing. So if ShowCalendarCloseButton is set to true and AllowCalendarClosing is set to false, the button will be displayed but will be disabled.Target Platforms: Windows 10, Windows 8.1, Windows 8, Windows 7, Windows Server 2012, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
