Remarks

Use the SelectionMode property to specify the date selection mode on the Calendar control. This property is set with one of the CalendarSelectionMode enumeration values. You can specify whether the user can select a single day, a week, or an entire month, or you can disable date-selection capability entirely.

When this property is set to CalendarSelectionMode.DayWeek or CalendarSelectionMode.DayWeekMonth, an additional selector column that contains week and month selection controls is displayed in the first column of the Calendar control. Use the SelectorStyle property to customize the appearance of this column.

To disable date selection, set this property to CalendarSelectionMode.None.
