i tried

navigationservice.goback();

navigationservice.removebackentry();

navigationservice.navigate(new uri(string.format("/accounts.xaml?refresh=true"), urikind.relative));

but nothing worked wanted please help

navigationservice.goback(); right way. problem need focus on is: "how refresh data when going accounts page". solution depends on application's architecture. if used mvvm pattern, it's matter of adding new account data source in viewmodel. otherwise, should reload account list in onnavigatedto method of page:

protected override void onnavigatedto(navigationeventargs e) {     // load accounts }
