How robust is the support for context menus on a treegrid? Essentially,
I’m using a 1 column grid with a tree column and I want different context menus
to show up depending on which tree level is being clicked on. I couldn’t
readily find information on how to do so. I tried using the
setOnBeforeContextMenu(func), but that seems to disable the menu (menu doesn’t
show up). Where can I add conditions that will help me decide which menu should
be displayed and whether a menu should be
displayed or not.
Also, if I set a column type to tree, can I also
make that column read-only?
