webbrowser control - Windows Phone 8 SDK - Issue with screen locking, and application starting over -


i have application webbrowser control in it. when navigate in control step away bit, come (after unlocking screen due inactivity), first/original page shows again. how can maintain state of browser?

define public property url in app.xaml.cs store url

public uri url { get; set; }

on webbrowser_loadcompleted event: save webbrowser.source property contains current loaded url above url property of application class.

app app = application.current app;  app.url = webbrowser.source;

on application_deactivated event (send app background), save current app's state isolatedstorage

isolatedstoragesettings settings = isolatedstoragesettings.applicationsettings; settings["url"] = url; settings.save();

on application_launching event (resume app), pull stored data back

isolatedstoragesettings settings = isolatedstoragesettings.applicationsettings; url currenturl; if (settings.trygetvalue("url", out currenturl))     url = (uri)settings["url"];

then restored url, can re-load last navigated page.

app app = application.current app; webbrowser.navigate(app.url);
