Bea shows how to implement expand/collapse all nodes and reveal-a-node TreeView functionality.
"In my last post, I showed how you can expand all items in a TreeView at load time. In WPF, this can be done by simply adding an implicit style to the resources, and in Silverlight we need a little help from ImplicitStyleManager to achieve the same behavior. However, applications typically allow more complex interaction with a TreeView. In particular, they often permit users to expand all nodes, collapse all nodes, and expand the tree to reveal a particular node. I will show you one way to accomplish these tasks in this post, and a different way in my next post."
