In your NodeView / TreeView  (this example is from a NodeView)
##########
  [GLib.ConnectBefore]		
  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;
      if (node is EnterpriseListNode)
        enterprise = ((EnterpriseListNode)node).Enterprise;
      else return;
      /* Is the click a right-button */
     if (_args.Event.Button == 3) 
     {
       PopupMenuBuilder  menu;
       menu.Append("Edit", enterprise, 
                   newEventHandler (EnterpriseEdit), 
	      	   (OnEnterpriseEdit != null));
   ....
      menu.Run();
  }

I cheat a little bit by having my own PopupMenuBuilder class; mostly
because the delegate needs the item represented by the node/row that was
selected in the view.
