Determines how many items can be selected.
The following sample demonstrates some of the properties and events related to selecting dates within the XamMonthCalendar.
For an overview of how to handle events in Visual Basic or Visual C#, see
Event Handlers in Visual Basic and Visual C#. For specific information and code examples illustrating how to consume events in your application, see
