How to use a derived CTreeCtrl in a CTreeView?

It is similar with this article: “How to use an derived CListCtrl in CListView” or “How do I subclass the CListCtrl part of a CListView Class?“.

Just like CListView, there is no CTreeCtrl to subclass in CTreeView. The CTreeView is the subclass of the WC_TREEVIEW common control. If you need some extra feature in the CTreeView, the best way is like the method mentioned in the previous two articles:

Forget CTreeView and derive your own view CMyView from CView, and bond your CMyTreeCtrl in the view. Now you got the full control of the tree.
