UWP AdaptiveTrigger不觸發

我在根網格內有VisualStateManager，但它沒有觸發AdaptiveTrigger。我正在嘗試更改StackPanel中的textblock。另外，VisualState制定者優先於默認值的規則是什麼？例如，textblockCreateNewAccount正在使用x:Uid獲取字符串資源，但當setter試圖更改Text值時，哪一個獲得優先級？與由FontSize設置靜態資源樣式相同。 UWP AdaptiveTrigger不觸發

我試過你的樣品，和* AdaptiveTrigger *似乎觸發 - 首先我看到從資源的文本，然後窗口後調整我看到從觸發值。你看起來如何？ – Romasz

@Romasz嘿。是的，它確實觸發。我意識到了這個問題。我正在測試一個移動模擬器，即使它是720p，但它不是那裏。我在桌面上進行了測試，並調整了它的工作寬度。我也意識到MinWindowWidth屬性表明最好先設計一個小的外形因子，然後使用AdaptiveTrigger設置器對較大的寬度和高度進行更改。我正在做相反的事情。 – ShrimpCrackers

最好是設計用於小形狀因數，並使用AdaptiveTrigger對於較大的寬度和高度。因爲我正在做相反的事情，並在較小的手機屏幕上進行測試，所以我無法看到這些變化。下面是修改後的XAML：

當窗口大小改變時，它似乎可以工作。那麼你的問題是什麼？ –
