Question

我创建了一个基于网格的XAML页面。在网格中，我显示的图像不需要负上边距，垂直值。在我的页面中，我在文本块中有两个标签，这些标签在网格堆栈面板中不能正确对齐，而在文本块中使用负顶边距值。第一个标签文本块我必须使用Margin =“0，-35,0,0”，第二个我必须使用Margin =“0，-650,0,0。XAML在下面请帮助。

Answer 1

您的代码有两个问题：

1）使用DockPanel时，您无法破坏Visual Tree。这意味着您对接的控件必须是DockPanel的直接子控件。例如：

<DockPanel>
    <Image DockPanel.Dock="Left" ... />
    <Label DockPanel.Dock="Right" .../>
</DockPanel>

否则DockPanel将无法再查看/停靠它们。网格和子列/行设置也是如此。

2）您正在包装Container中的每个Control。如果没有必要，它只会污染视觉树，在这种情况下打破你想要做的连接。

重构后，不再需要负边距：

Answer 2

正如我在帖子中所述，我在XMAL中使用负边距值来定位控件。为了防止在包含嵌套网格的StackPanel中正确使用网格，可以进行正确的垂直对齐。

现在要注意水平对齐使用以下技术将处理这个问题：

<StackPanel Orientation=Vertical />
    <StackPanel Orientation=Horizontal />
        content.....
    </StackPanel>
 </StackPanel>

使用负高度边距值正确垂直对齐控件
