'Declaration Public Property SelectionMode As CalendarDateSelectionMode
public CalendarDateSelectionMode SelectionMode {get; set;}
The default selection type is Extended which allows multiple discontinuous ranges of dates to be selected. As dates are selected, the CalendarBase.SelectedDatesChanged event is raised and the SelectedDate and SelectedDates properties are updated. When using a multiple selection type such as Extended or Range, you can use the MaxSelectedDates to control the maximum number of Infragistics.Controls.Editors.Primitives.CalendarItem instances that the user can select.
