This is a first approach at dealing with the issue of taking expanded children (and grand-children) into account when determining an offset into the InternalItemsSource.
I also split up the move tests into move up and down variants. It is only the tests with expanded children that fail.
"Fixed" by delegating the responsibility of the move operation out to the TreeListView which has a concept of containers. This allows us to reuse the Collapse->Move->Expand approach which is used when moving nested items around.
Does this work? Fixing event leaks We can collapse.... but this seems like cheating.
Better implementation that doesn't provoke the disconnected item. Fixed cleanup issues with the containers. All tests are passing :)
I may be wrong here, but I believe the <VisualState> storyboards should not have a duration. I believe these will be invoked when VisualStateManager.GoToState() is called with useTransitions=false. Thus I believe animations (durations) should only be used in the <VisualTransistion> storyboards which is invoked when VisualStateManager.GoToState() is called with useTransitions=true.
Fixed issue with replacing the last item. Added additional replacement tests

does it work well with virtualization? |

Yea, because it is just a list view, as long as it has virtualization enabled it works well for that. |

This control is based on a ListView NOT a TreeView.
The interaction is expected to be similar to a TreeView with a HierarchialDataTemplate, but the rest of the UI should match ListView behavior.
At present there is no support for ListView.GridView.
