Implementing multiple selection on TreeView using checkboxes

Question

How do I make it so that when a user selects a tree node, all of the ones under it will be selected? Is this something I am missing in the properties, or do I have to code this?

Your comments to Nickolay's answer indicate that you're using checkboxes on your TreeView. Is that assumption correct, or are you trying to make multiple items appear selected (i.e., highlighted)? Multiple selection is a way bigger hassle if you don't want to use checkboxes. — Cody Gray

It seems that you should code that, it's quite simple, just handle OnChange event of tree node, and set .Checked to all it's siblings.

well then how do I handle a "half checked" kind of thing? Like where only some of the children are checked and so the parent usually has a box in it?

That can be also handled via OnChecked event, just update value of parent nodes to checkState.Indeterminate if not all of it's siblings are checked.
