Which event to use

[Naomi]

Hi everybody,

I have a TreeViewWrapper control on the form. It allows multiselect. I
need to implement one logic when only one item is selected - this
logic is already implemented in the NodeClick event.

I'm trying to find out which event fires when user selected all items
he/she needs and is ready to perform some operations. Do I need to try
to implement this logic in the LostFocus event of the TreeViewWrapper?
Or what would be the best place for this logic?

Thanks in advance.
