Windows phone application hardware back button click function not trigger??

+2 votes

so as of now when a back (hardware) button is clicked it closes the app. How can I work around this so it goes to the previous webpage or goes back to the index or something on those lines?

Use This method:

   protected override void OnBackKeyPress(System.ComponentModel.CancelEventArgs e)

        //Do your work here

        e.Cancel = true;

        var result = MessageBox.Show("Do you want to exit?", "Attention!",

        if (result == MessageBoxResult.OK)
            NavigationService.Navigate(new Uri("/MainPage.xaml", UriKind.Relative));
        e.Cancel = true;

       // base.OnBackKeyPress(e);

also it works fine, write CanrevertState() as below:

bool CanRevertState()
return true;
and call this CamRevertState() where you need , it just navigate to previous page you visited even when you touch phone's hardware button .
