I am having trouble with a treeview control that is being used on 2 of the 6 pages on a pageframe. And this is sitting on top of a form. What is happening is that on the last page I instantiate another class and then execute the show method of the new object. when the show method fires the treeview controls get screwed up. Particularly the selected property, probably others if not all, go from being a valid object null. The only thing that I can think to do is store the controls property values and restore them prior to accessing them but its not what I would prefer to do. Any suggestions??
