Using comboboxes in the MFC Grid Control Since I posted my MFC grid control I ve had a lot of requests asking how to use other methods of editing cells in the grid. Ken Bertelson has taken this to the extreme, with his Grid Tree control. For some this was a little too involved, so I ve created a demo project that shows how to replace the default editing with a simple combo box. Previous methods of achieving this required that a new CGridCtrl derived class be created. With the new structure in the 2.X versions of CGridCtrl it s now a lot simpler. -Using comboboxes in the MFC Grid ControlSince I posted my MFC grid control I ve had a lot of requests asking how to use other methods of editing cells in the grid.
