Typically, a Windows Phone 7 application uses form navigation similar to the Silverlight navigation application hosted in a browser. This allows you to return to the previous phone button from the "pages" to which the transition was made.
Your form Jeansshould actually be inferred from PhoneApplicationPageand should have a simple default constructor (not the one that takes the parameter as you are now).
: -
NavigationService.Navigate(new Uri("/Views/Jeans.xml?name=Elwood%20Curtis"));
"" OnNavigatedTo: -
protected override void OnNavigatedTo(Microsoft.Phone.Navigation.PhoneNavigationEventArgs e)
{
base.OnNavigatedTo(e);
Name = NavigationContext.QueryString["name"];
}
