控件不适合调整 WPF 的大小

Question

我正在尝试创建一个响应式应用程序，我所做的所有努力都没有在新标准 WPF 上给我带来结果。 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。 如何创建可以自动调整控件的应用程序？在正常形式上，我这样做没有问题，但在 WPF 中并不真正了解如何自动适应，尽管阅读了许多教程。谢谢。

                                <DataGridTextColumn Binding="{x:Null}" ClipboardContentBinding="{x:Null}" Header="S"/>

                    </GroupBox>
                    <GroupBox Grid.Column="1" Header="item2" HorizontalAlignment="Stretch" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch">

                                <DataGridTextColumn Binding="{x:Null}" ClipboardContentBinding="{x:Null}" Header="Book" MinWidth="80" />

                    <GroupBox Grid.Column="2" Header="item3" HorizontalAlignment="Stretch" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" >
                        <StackPanel Orientation="Horizontal">
                            <RadioButton Content="1t" />

                    </GroupBox>
                </Grid>
            </TabItem>
            <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 与比例或自动列一起使用。
