Is it the standard of the Microsoft common treeview controls to place a
plus or minus box (what're those technically called anyway?) to the left of
a parent that has no children in a tree view?

Can anyone give me a document reference of this behavior? I've got to
prove this to my PM.

Thanks!

Just have him look at Windows Explorer (but hide IE's Favorites list and IE
advanced properties dialog from him/her)

Bottomline, there is no standard there -- the plus/minus signs are an option
you can turn on or off, depending on your application needs.

I have a root level item displayed and it is expanded. Some of the next
level items have children and some do not, but all of them have a
plus/minus box next to them, and all of the boxes contain plus signs. When
I click on the plus sign of an item that has no children, the plus sign
remains, it never changes to a minus.

In addition, if I expand one of these 2nd level items, some of my 3 level
items have children and some do not. But at this level, the boxes seem to
work similarly to explorer. The 3rd level parents that have children have
a plus sign beside them, while the 3rd level childless parents have no box
at all beside them.

I hope I'm communicating this well enough. Is this a known situation?

Thanks again!

Habitually this is done when you have a tree dynamically build to gain some
performance. You assume that they are children but if you really want to
know you must go there to retrieve the data if any.
