I am using a ttreeview component.
I have many parent nodes each of which
has four child nodes. My question is
how can I determine the parent node
of each child in a way that will not
produce an exception if the selected
item is the parent. I am able to
get the parent when a child node is
selected, however, if you have the
parent already selected, the program
(index) produces an exception. I don't
really understand ttreeview. Can anyone
help. (Sorry for rambling!).
