Initially the ListViewItem is born with a null parent;  When the parent
adds the individual items, it will call a method to set the parent,
something like this:

class ListView {

	Add (ListViewItem item)
	{
		item.SetParent (this);
	}
}

class ListViewItem {
	ListView parent = null;

	public ListView ListView {
		get { return parent; }
	}

	internal SetParent (ListView p)
	{
		parent = p;
	}
}
