TreeView Selection Update

[enisn]

Happy to introduce that TreeView has built-in line selection now. There was already checkbox selection, but it's a different approach.

You can watch the tutorial:

I'm not able to get a propertychanged notification when I use multiple selection and bind selectedNodes.
If the event would be public, then maybe I could use this to have access after selectionUpdate
