Hi,
I have a treeviewer to display a long list of tree objects. When the
platform starts again, I would like to the treeviewer to scroll to the last
position(or page) the user has worked, so that giving the user the feeling
that the system has exactly load last state. Is there a way to do that?
Thanks
Eric

Thank you, Richard. It's a good thing to save it in IMemento, but my tree is
too big to be saved. Furthermore, if the platform is not shut down and the
tree is refreshed(some nodes added or removed), do I have any way to
remember current position and scroll back.
