I have a winform program that contains a GoView control which is displaying a GoLayoutLayeredDigraph. So far so good. I now need to be able to save and restore the document/view contents many times over as the user requests different graphs to display and edit. Is there any example code to do this or maybe a how-to document? Do I need a seperate GoView control for each graph? I only need to display a single graph at any point in time.
