How do you create expandable properties using custom IDataAccessor implementations?

Hi Magnus,

Property expandability normally depends on the TypeConverter associated with a property value returning that the value has properties, via its GetPropertiesSupported method returning true, and its GetProperties method returning additional properties.

But if you are using a custom factory, it's easy to add child properties.  The factory's GetProperties method is called when each property is being readied for display.  You can simply return a list of child data accessors for it.  You can see in our QuickStart how we make a list of custom child data accessors for any property of type CustomerViewModel.  The same sort of thing could apply to any other type.
