You need to understand that almost all of the WinForms controls are just (often thin) wrappers around an underlying Win32 API control. The Win32 ListBox comes from old Windows 1.0. The Common Control ListView was created by my friend John Kallen along with Chris Guzak for Windows 95. Different generation of controls with different design philosophies and objectives.
