About the demo
If you have a navigation tree where every node redirects to another page with the same tree (*) and want to preserve tree state (expand / collapse state, selected node, check state, scroll position), set PassTreeStateOnChangeLocation="true" for the tree on every page. The tree on the other page will restore its state from request parameters.
(*) The trees should have the same ID. The trees should have the same structure OR corresponding nodes should have the same IndexKey.
