Could you, please, explain in a bit more detail what exactly is the scenario you try to implement?
The page that is initially posted as an example of recursive expand isn't meant to be one.
If I understood the problem correctly, the best solution, would be to expand more than one node on NodeExpand event on the server (as many nodes as needed), considering the state of the node that the event was initially thrown for.
Hope this is helpful for you. Of course if this is not what you are looking for, please further explain what seems to be the problem.
