Non-hyperlinked text in a treeview

[John Bankhead]

I have a simple treeview (four levels deep) that I am building manually when
the page is loaded. I am trying to figure out how to take the treeview out
of navigation mode. That is to say that the text for a node should NOT be a
hyperlink. According to all of the docs I have found, setting the
NavigateURL to an empty string will do this for me. This does not seem to
work.

suggestions?

My Original Code:
TreeNode _root = new TreeNode("Fault Code Filter");
tree.Nodes.Add(_root);

Tried this:
TreeNode _root = new TreeNode("Fault Code Filter","-1","","","");

And this
TreeNode _root = new TreeNode("Fault Code Filter","-1","","","");
_root.NavigateUrl = "";

Also this:
TreeNode _root = new TreeNode("Fault Code Filter","-1","","","");
_root.NavigateUrl = null;
