Question

我是WPF的新手，似乎无法正确显示我的表单。我预计会有6行。前三个应该有按钮，最后三个包含更多的网格。我正在关注NHibernate电子书中的代码，但它似乎没有正确显示。有人可以看看这段代码并提出任何可能的错误：

Window

Answer 1

最后一个网格与第5行的网格重叠，即：

<av:Grid x:Name = "ProductGrid" Margin="-1,2,1,130" av:Grid.Row="5">
<av:Grid x:Name = "LoadCategoryGrid" av:Grid.Row="5" Margin="3,73,-3,128" >

将两个网格放在同一网格行中，查看具有相同值的av:Grid.Row附加属性。要在空闲位置移动其中一个，必须更改为：av:Grid.Row="4"

Answer 2

除了定义了只有一行的Grid.Row="5"和Grid.RowSpan="2"的迷路双重定义之外，你现在已经修复了这两行，唯一会影响定位的其他代码就是所有假的{{ 1}}值。

除此之外，XAML看起来很好。
