vb.net nested class' parent?

is there an implicitly-defined Parent property defined for a class that is
nested in another class? i'm looking to simplify my coding.

At this point, i've defined the class as so:

Class Item

    Private _SubItem As New SubItem(Me)

    'other properties and methods

    Class SubItem

        Private _Parent As Item

        Public ReadOnly Property Parent As Item
            Get
                Return _Parent
            End Get
        End Property

        Friend Sub New (value as Item)
            _Parent=value
        End Sub

        'other stuff

    End Class

End Class

Thanks,

Craig Buchanan

There isn't an implicit reference to the containing object. You will
need to pass that in yourself in your nested class's constructor.
