Wpf 选项卡内的重叠网格

我在一个TabItem中有两个网格，在后面的代码中，我希望能够将控件添加到两个网格中，并使所有控件在运行时可见。当前在运行时，添加到Grid3的控件不可见，而添加到Grid4的控件可见

重叠轴网具有相同的行，但具有不同的列集

我试图用两个网格来实现这一点，这样我就可以通过将控件添加到两个网格中的一个来改变代码中每行可以添加的控件数量

以下是XML：

XML中的控件只是我在代码后面的网格中添加的控件的占位符

如果有人能提出解决方案，我将不胜感激

谢谢

您的InnerTabControlGrid不定义任何行或列定义，因此两个子网格在一个网格单元中相互重叠

---

将InnerTabControlGrid更改为DockPanel或UniformGrid，或为其指定一些Grid.ColumnDefinitions或Grid.RowDefinitions，并指定子网格的Grid.Column或Grid.Row

从网格中删除背景。纯色是看不透的。

谢谢！这就是问题所在。
