You're not using current CVS, are you?

Because this signature:
> public void OnTreeview1RowActivated(object o, EventArgs args)

is now:
public void OnTreeView1RowActivated (object o, RowActivatedArgs args)

Apart from this, you can get the 'activated' value with something like:

> {
> label1.Text = "Toto";
> statusbar1.Pop(1);
> statusbar1.Pop(0);
  TreeView tv = (TreeView) o;
  TreeModel model = tv.Model;
  TreeIter iter;
  model.GetIter (out iter, args.Path);
  GLib.Value val;
  model.GetValue (iter, 0, out value);
  statusbar1.Push(0,"Selection made: " + (string) value);
