Animation Windows Phone emulator不显示任何动画/移动

我在Blend4中准备了最简单的应用程序，我将文本框放入添加的故事板keyframe1中，移动文本框并添加另一个关键帧。动画在Blend4中工作，我在情节提要上按play，文本框移动。我运行了模拟器，但它没有运行。我甚至运行了我老师的应用程序，它也不会动画（应该）

我该怎么做才能让它运行呢

如何从代码开始动画？？
F.E.翻转动画：

XAML

看得见的
看得见的

启动动画的CS代码：

---

VisualStateManager.GoToState（这是“展示”，正确）

我怎么开始呢？我在blend的故事板中创建了它，它应该会运行。因为我理解了动画必须从某个事件开始。在blend U运行动画手册中，按下播放按钮。因此，动画必须如何以及何时在amulator中启动。本文可以帮助您查看这个示例。
