I set IsExpanded = false of the RadTreeViewItem in code.
The nodes are unfold but positions are not adjusted. they just unexpand their sub nodes only.
Then I expand the sub nodes and unexpand them again by hand (not code), they shrank as I expected.
How can I adjust position of unexpanded nodes that are modified by IsExpanded = false code?
