Customizing the TreeView to allow multi select

Question

The built-in WPF TreeView control does not allow for multi selection, like a ListBox does. How can I customize the TreeView to allow for multi selection without rewriting i

Answer 1

When I consider overriding the fundamental behavior of a control, like a treeview, I always like to consider the usability and effort associated with my decision.

In the specific case of a treeview I find that switching to a listview in combination with zero, one, or more controls makes for a more usable solution that often is easier to implement.

As an example, consider the common Open dialog, or Windows Explorer application.
