Question

我在网格中有两个ListBox。 ListBox ItemsPanelTemplate设置为“WrapPanel”。我期待看到两个单独的行，但只看到1.我对xaml很新。非常感谢您的帮助。感谢。

我认为您没有指定第一个列表框属于网格行0而第二个列表框属于网格行1。 0附加属性的默认值为Grid.Row，因此您无需为第一个列表框指定它。但是对于第二个，您需要将其明确设置为1：

<ListBox Name="machines" Grid.Row="1" ... >
  ...
</ListBox>

我没有看到我的一个网格行....（XAML网格中的两个WrapPanel ListBox）
