我有一个布局,其中两个列的屏幕尺寸更宽,当应用程序调整为较小的尺寸时,右列位于左列下方。这可以使用StateTriggers来更改ColumnSpan和Row,如下面的代码所示。
这很好用,除了我希望并排时可以单独滚动列,但是当切换到顶部/底部时,我希望整个内容可以一起滚动。
我在每列的内容周围都有一个根ScrollViewer和ScrollViewers。我正在根据屏幕大小启用/禁用根卷轴,这是有效的,但嵌套的ScrollViewers无法正常工作。
如果我遗漏了某些东西,或者有更好的方法来进行此布局,请告诉我。

更新:我仍然无法找到解决方法。如果有人对这种方法有一些意见或者可以推荐不同的方法,那就太好了。

使用ScrollViewer可以将内容显示在比实际大小更小的区域中。在您的代码中,嵌套网格(Column1Grid)的内容大小是自动设置,因此无法显示滚动查看器。一个简单的解决方案是根据后面代码中窗口的大小动态设置高度,如下所示:
public CChangeView()
{
this.InitializeComponent();
Window.Current.SizeChanged += Current_SizeChanged;
}
private void Current_SizeChanged(object sender, Windows.UI.Core.WindowSizeChangedEventArgs e)
{
Column1Grid.Height = Window.Current.Bounds.Height;
Column2Grid.Height = Window.Current.Bounds.Height;
}
