Windows phone 7 是否可以使用appbar弹出sigin/up页面（pivot）？

是否可以使用appbar弹出sigin/up页面（pivot）？是否有可能自动填充屏幕（是否有系统托盘）？

有可能

要在主页中打开弹出窗口，请使用（加载页面时的弹出窗口示例）：

在数据透视页中，创建添加构造函数：

    private PhoneApplicationPage parent = null;
    private IApplicationBar parentAppBar = null;
    private Popup popup = null;

    public PivotPage1(double w, double h, PhoneApplicationPage p, Popup pop) : this()
    {
        Width = w;
        Height = h;
        parent = p;
        popup = pop;

        Loaded += (obj, args) =>
            {
                parentAppBar = parent.ApplicationBar;
                parent.ApplicationBar = this.ApplicationBar;
            };

        Unloaded += (obj, args) =>
            {
                parent.ApplicationBar = parentAppBar;
            };
    }

    private void menuItem3_Click(object sender, EventArgs e)
    {
        popup.IsOpen = false;
    }

如果你想要全屏和appbar，为什么不导航到一个新页面呢？@KooKiz u应该读一下这篇文章：

    private PhoneApplicationPage parent = null;
    private IApplicationBar parentAppBar = null;
    private Popup popup = null;

    public PivotPage1(double w, double h, PhoneApplicationPage p, Popup pop) : this()
    {
        Width = w;
        Height = h;
        parent = p;
        popup = pop;

        Loaded += (obj, args) =>
            {
                parentAppBar = parent.ApplicationBar;
                parent.ApplicationBar = this.ApplicationBar;
            };

        Unloaded += (obj, args) =>
            {
                parent.ApplicationBar = parentAppBar;
            };
    }

    private void menuItem3_Click(object sender, EventArgs e)
    {
        popup.IsOpen = false;
    }
