thanks!

if using winrt can write following code in page constructor cache it, way positions intact after go page:

this.navigationcachemode = navigationcachemode.required; 

and sample cant see if using listbox or listview, presume listview better listbox not needed anymore.

one thing noticed use simple {binding} itemssource maybe reset every time go because of (if doing this, not visible sample code). have additional property of type observablecollection , bind example itemssource={binding myitems}. way list reset when reset property myitems.
