我使用设置模板属性为类型Window创建了样式。如果我为窗口设置高度和宽度属性，它工作正常。但是当我试图设置SizeToContent =“WidthAndHeight”时，窗口的高度和宽度被设置为屏幕的全高和宽度（即使窗口的所有内容都受到高度和宽度的限制）。可以在控件模板中处理SizeToContent吗？
这是窗口样式：

<Setter Property="WindowStyle" Value="None" />
<Setter Property="Background" Value="Transparent" />

看起来您遇到的问题是内容没有大小，因此它占用了最大可用空间，对我来说，它将宽度设置为我的两个屏幕的组合宽度。
你基本上有这样一种情况：窗口会说“我会尽可能多地接受你需要的内容”，而内容却说“我会尽可能多地给你一个窗口”，所以Window正在服用这一切。
编辑：实际上，如果要删除包含网格上的边距，然后删除具有ActualHeight / Width绑定的行，那么它将解决您的问题。看起来模板的这两个方面正在推出尺寸，直到达到最大值。
