Been using your TKGrid, nice. I expect a more codeless approach for assigning editor, though. I hope it can be assigned per column in a form designer. I'm rewriting one of my software, a questionnaire system. Previously I use scrollable panel with proper childsizing to layout the interface, but that sucks. It would be better using a grid, but no grid component offers such a functionality yet. At least checkbox, radio and text edit required.
