当我按下WPF应用程序上的“最大化”按钮时，其中的所有控件都完全水平扩展，但它们不会展开以垂直填充窗口。我认为最大化水平处理它，它也应该垂直处理它。我应该在每个控件的某处设置属性吗？我可以捕获Resize事件，但是通过所有控件并仅垂直调整它们似乎需要做很多工作。
感谢您的帮助。

FYI。我最终将网格的高度更改为“自动”，然后当Window1的SizeChanged事件触发时，我将网格高度设置为e.NewSize.Height减去StackPanel中位于其上方的控件的ActualHeights 。不是我希望它如何，但到目前为止，我发现唯一有效的解决方案。
感谢。

你能告诉我们一些Xaml吗？尝试将外部容器设置为VerticalAlignment =“Stretch”
答案 2 :(得分：0)
预览窗口会切断部分XAML，但会在答案文本框中显示确定。如果遇到好的话请告诉我。 VerticalAlignment =“拉伸”没有帮助。

答案 3 :(得分：0)
当您调整窗口大小时，有问题的控件是否会缩小/垂直增长？
您正在将网格的高度属性设置为“390”，这使其垂直固定大小。如果这是你对其他一切的“父母”控制，那么他们将从中获得关键。
答案 4 :(得分：0)
是的，这是我调整窗口大小时不会垂直收缩/增长的控件。
自从我写完以来，我将网格高度更改为auto，当我运行我的应用程序时，网格，因为它是StackPanel中的最后一个控件，只占用窗口中剩余空间的一部分首先显示 - 可能是390中的80个。在第0行，第0列，我有一个自定义面板（theGraphPanel），我在其中绘制一个圆形节点。如果我绘制20个节点，那个单元格大小适当，甚至在最大化时占据整个屏幕。这有点解决了这个问题，虽然垂直滚动不起作用，因为我认为它认为它有无限的高度。
当我将大小设置为390时，我希望网格显示在屏幕上的方式 - 第一行占用剩余空间的高度3 *，第二行占用*高度。我想我想要做的是模拟MDI设置。当我第一次启动应用程序（800 x 600）然后当我最大化它时，我希望比例保持不变。据我所知，除非网格单元具有内容，否则它们将保持最小尺寸并且在整体网格高度设置为“自动”时增长到内容的任何大小。也许我正在尝试做一些不可能的事情。
感谢目前为止的答案。
