Pivot 上的控件消失

我有一个应用程序，有一个枢轴控制。Pivot 控件有两个项(页) ，都包含 grid。网格包含几个按钮，一个是地图，另一个是文本块。当应用程序第一次运行时，枢轴工作正常。然而，当应用程序运行一段时间(比如一天)后，枢轴上的所有控件在枢轴(或滑动)之后都会消失。它们在滑动时会暂时出现，但是一旦支点停止，它们就会再次消失。

有其他人经历过这种情况吗? 原因和解决办法是什么？

Quite old question, but still unanswered. It seems like it's because of Application_Deactivated event handler, which runs when application is sent to background:

private void Application_Deactivated(object sender, DeactivatedEventArgs e)
{
diagLog("Deactivated, reason: " + e.Reason);
}

In this event handler you should set RunningInBackground = true

Hope that helps

I am facing the same issue, and its solved weirdly.

If I use Grid inside PivotItem this Issue comes but when I use some other control like StackPanel or something else it works fine.
