Mike Lischke's Virtual Treeview component suite. Virtual Treeview is a very flexible treeview control. The control uses a "virtual node" paradigm to achieve impressive run-time performance.

The virtual paradigm defers formal initialization until absolutely needed for display purposes. See the Virtual TreeView subsection on this wiki: VT Home
