控件不适合窗体大小调整 WPF

Question

我正在尝试创建一个响应式应用程序，但我所做的所有努力都没有在新标准 WPF 上产生结果。当表单缩小或展开时，我会确保调整应用程序控件的大小。正如您从图片中看到的那样，当表单缩小时，项目 3 并不完全可见，因此不适合用户给出的新尺寸。如何创建一个可以自动调整控件的应用程序？在正常情况下，我这样做没有问题，但在 WPF 中并不真正理解如何自动适应，尽管阅读了大量教程。谢谢。

            <TabItem Header="tab2">
            </TabItem>
        </TabControl>
    </Grid>
</Window>

结果：

对所有 WPF 程序员的最后评论：不要使用 Canvas 并避免硬编码 Width、Height 和其他此类属性。将 Grid 与 proprotional 或 Auto 列一起使用。
