The Schedule class represents the data displayed by MindFusion.Scheduling for Silverlight calendar views. The schedule contains a collection of schedule items defined by the Item abstract class and implemented by the Appointment class. Appointment objects contain references to instances of the miscellaneous Task, Location, Contact and Resource classes, which are also contained in the respective collection members of the Schedule class.
If your application has to process other types of schedule data items, create a class for each item type and inherit it from Item or Appointment. All methods and properties defined in Item are abstract, so if a class inherits from it, that class must implement all members of the Item class. On the other hand, if a class derives from Appointment, it can just add its own distinct properties and override the SaveTo and LoadFrom methods to implement serialization of the new members of the class. Custom schedule item classes must be registered for serialization via the RegisterItemClass method of the Schedule.
