This is working for me, at least with a NodeView.

public void OnButonPressEvent(object_sender, ButtonPressEventArgs args)
  ITreeNode	node;
  Enterprise	enterprise;

  if (PopupEnabled) {
    /* Get the selected list node from the nodeview
       and bail out if result is not a EnterpriseListNode */
    node = (_sender as NodeView).NodeSelection.SelectedNode;
