轉換Transition

<StackPanel>
<StackPanel.ChildrenTransitions>
<TransitionCollection>
<EntranceThemeTansition></EntranceThemeTransition>
</TransitionCollection>
</StackPanel.ChildrenTransitions>
</StackPanel>

動態添加元素到StackPanel中，就會有EntranceThemeTansition的動態效果。

跳轉頁面也會有這些轉換效果：

<Page>
<Page.ChildrenTransitions>
<TransitionCollection>
<EntranceThemeTansition></EntranceThemeTransition>
</TransitionCollection>
</Page.ChildrenTransitions>
</Page>
