UWP AdaptiveTrigger不触发

我在根网格内有VisualStateManager，但它没有触发AdaptiveTrigger。我正在尝试更改StackPanel中的textblock。另外，VisualState制定者优先于默认值的规则是什么？例如，textblockCreateNewAccount正在使用x:Uid获取字符串资源，但当setter试图更改Text值时，哪一个获得优先级？与由FontSize设置静态资源样式相同。 UWP AdaptiveTrigger不触发

我试过你的样品，和* AdaptiveTrigger *似乎触发 - 首先我看到从资源的文本，然后窗口后调整我看到从触发值。你看起来如何？ – Romasz

@Romasz嘿。是的，它确实触发。我意识到了这个问题。我正在测试一个移动模拟器，即使它是720p，但它不是那里。我在桌面上进行了测试，并调整了它的工作宽度。我也意识到MinWindowWidth属性表明最好先设计一个小的外形因子，然后使用AdaptiveTrigger设置器对较大的宽度和高度进行更改。我正在做相反的事情。 – ShrimpCrackers

最好是设计用于小形状因数，并使用AdaptiveTrigger对于较大的宽度和高度。因为我正在做相反的事情，并在较小的手机屏幕上进行测试，所以我无法看到这些变化。下面是修改后的XAML：

当窗口大小改变时，它似乎可以工作。那么你的问题是什么？ –
