WPF frame RemoveBackEntry

Site Index
あれこれやってみて妥協。前１ページは残して最新ページを表示するため Refresh と RemoveBackEntry を使用。








public partial class MainWindow : Window

{

    public MainWindow()

    {

        InitializeComponent();

    }

    int z_count = 0;

    private void button1_Click(object sender, RoutedEventArgs e)

    {

        Window1 w_window = new Window1();

        Page1 w_page = new Page1();

        z_count++;

        w_page.button1.Content = "Count " + z_count;

        this.frame1.Content = w_page;

    }

    private void button2_Click(object sender, RoutedEventArgs e)

    {

        this.frame1.Content = null;

        this.frame1.NavigationService.RemoveBackEntry();

        this.frame1.Refresh();

    }

    private void button3_Click(object sender, RoutedEventArgs e)

    {

        Window1 w_window = new Window1();

        Page1 w_page = new Page1();

        z_count++;

        w_page.button1.Content = "Count " + z_count;
        this.frame1.Content = null;

        this.frame1.NavigationService.RemoveBackEntry();

        this.frame1.Refresh();
        this.frame1.Content = w_page;

    }

}
