Hi, I have a treeview with custom treeviewitem. I would like to do some animation when this item is collapsing. But not kind of closing nod. Collapsing like visibility changing (visible/hidden/collapsed). I trying to catch this event in a xaml, but have
no idea how. Only nod closing collapse is presented for treeviewitem. But what if I want to animate temporary collapsing an item rather than nod?..
