Question

如果您将此代码粘贴到新UWP应用程序的主页中（或查看第一张图片），您会发现橙色网格占用的空间超出了所需的空间（VerticalAlignment设置为顶部）。为了使其按预期工作，您必须将此网格的第2行高度设置为Auto（请参阅第2张图片）。问题是我想给第2行/最后一行提供额外的空间，而不是将它分配到所有行 将左侧列中的控件放在他们自己的网格中（显然，因为没有rowspan）但是我不能这样做，因为当屏幕缩小时，右列中的stackpanel会进入左列的一行内

第二个问题是，如果单击橙色/绿色/黄色空间，焦点将始终转到第一行的文本框（黄色）。

更新：两个问题都是在没有滚动查看器的情况下修复的，但我显然需要它。

Answer 1

我找到了解决方法。由于第一行不会扩展或更改，我将第一行的MaxHeight属性设置为等于行的实际高度。

对于第二个问题，请将滚动查看器的IsTabStop属性设置为True，如下所述：
