How can I change the appearance of a Winforms TreeView SelectedNode using C#?

I can set the Treeview selected node using code, but it's appearance does not change.

 TreeNode selectedNode = treeView1.SelectedNode;
 TreeNode newNode = new TreeNode("I am new");
 selectedNode.Nodes.Add(newNode);
 treeView1.SelectedNode = newNode;

When I select nodes using my mouse the backgr开发者_如何学Goound color and fore colors change. I want the same thing to happen when I select a node using code. How can I change the appearance of a Winforms TreeView SelectedNode using C#? Thanks!

Did you set HideSelection to false? For some reason the default value is true which will prevent the nodes from appearing selected unless the control has focus (which it of course will have when nodes are seleced using the mouse).
