c# - Cancelling navigation on a browser back button doesnt affect the Uri - Silverlight -

i cancelling navigation overriding method:

protected override void onnavigatingfrom(navigatingcanceleventargs e) { e.cancel = true; base.onnavigatingfrom(e); }

this works when using navigationservice.navigate(...)

but if user presses browser button, browser uri change, though page doesn't change.

how prevent uri changing on browser button?
