我在TabItem中有两个网格，在代码隐藏中，我希望能够向两个网格添加控件，并在运行时显示所有控件。目前在运行时，添加到“Grid3”的控件在添加到“Grid4”的控件可见时不可见。
重叠网格具有相同的行但具有不同的列集。
我正在尝试使用两个网格执行此操作，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我可以在代码隐藏中每行添加的控件数量。
这是XML：

XML中的控件只是我将添加到代码隐藏中的网格的控件的占位符。
如果有人能提出解决方案，我会很感激。
谢谢！

您的InnerTabControlGrid未定义任何行或列定义，因此两个子网格在一个网格单元格中相互叠加。
将InnerTabControlGrid更改为DockPanel或UniformGrid，或者将其设为Grid.ColumnDefinitions或Grid.RowDefinitions并指定您的子网格Grid.Column或Grid.Row

从网格中删除背景。你看不到纯色。
