This is a really neat feature in Explorer and I'd like to add it to my ListView, but I'm not sure how:
![]()
None of the documented styles for the header control do that. Anyone have any idea how to do it without having to resort to owner draw? I already have the modern headers in my listview, and it's already subclassed to provide standard right-click dropdown menus. So, even if I could just add the dropdown button? Then I could pop up a standard API-constructed check menu.
