C1Calendar supports a variety of selection options.

Date selection in month view is controlled by the SelectionMode property. TheSelectionMode property is an object that contains five Boolean type child properties, which are:

• Day
• Days
• WeekDay
• WeekNumber
• Month

For example, if we set the SelectionMode.WeekDay to True, then the weekday cell is selectable. If we want the week number selectable, we have to set the SelectionMode.WeekNumber and ShowWeekNumbers properties to True.
