XAML StackPanel 在其他页面裁剪项目

Question

我正在 VS 中构建一个 C# XAML 通用应用程序，在页面之间进行一些简单的导航。直到几天前，导航都工作正常，你可以点击主页上的一个按钮，它会带你到第二页，然后你可以点击第二页上的后退按钮，它 return你回到起点。现在，其他页面（不是主页）正在单独裁剪所有项目，因此小项目甚至消失了。后退按钮只是一个 200x200 像素的小图像，没有显示，并且在 'Timer' 页面上，计时器文本被裁剪了很多。这是编辑器中定时器页面的屏幕截图，然后是调试程序中的屏幕截图。

下面是来源。

我怎样才能让它停止裁剪？我做错了什么？

Answer 1

你完全搞砸了 xaml 布局。不知道你到底想达到什么目的。为了获得类似于您的第一个屏幕截图的布局，我将文本块的边距从 (Margin="494,151,639,184") 更改为 (Margin="494,151,0,0") 并将按钮的网格位置设置为

Grid.Column="1"
Grid.RowSpan="2"
