Answer 1

This is an interesting problem. I think that probably you will need to create a custom control that subclasses TreeViewItemand add a couple of dependency properties that the parent class does not provide.

TreeViewItem ItemsControl, Selector, SelectedItem SelectedIndex. . SelectedItem: , IsSelected , , Items , SelectedItem . SelectedIndex .

, - , - , 1, 0 TreeViewItem, , SelectedIndex ActualHeight, , , .

, , . , , SelectedItem . ( .) , , , SelectedItem null Parent . 1, 0 , , SelectedItem .

, , IsSelected : .
