问题描述

我如何在C＃/ WPF中的网格上放置边框？

How do i put a border on my grid in C#/WPF?

这就是我想要的样子，但是在整个对象周围都设置了边框

This is what i would like it to be, but puts a border around the whole thing instead of the grid control i put in my application.

<Grid>
    <Border BorderBrush="Black" BorderThickness="2">
        <Grid Height="166" HorizontalAlignment="Left" Margin="12,12,0,0" Name="grid1" VerticalAlignment="Top" Width="479" Background="#FFF2F2F2" />
    </Border>
... and so on ...

推荐答案

如果您只想要一个外部边框，最简单的方法是将其放在Border控件中：

If you just want an outer border, the easiest way is to put it in a Border control:

<Border BorderBrush="Black" BorderThickness="2">
    <Grid>
       <!-- Grid contents here -->
    </Grid>
</Border>

看到边框完全填满控件的原因是，默认情况下，它是Horizo​​ntalAlignment和将VerticalAlignment设置为Stretch。请尝试以下操作：

The reason you're seeing the border completely fill your control is that, by default, it's HorizontalAlignment and VerticalAlignment are set to Stretch. Try the following:

<Grid>
    <Border  HorizontalAlignment="Left" VerticalAlignment="Top"  BorderBrush="Black" BorderThickness="2">
        <Grid Height="166" HorizontalAlignment="Left" Margin="12,12,0,0" Name="grid1" VerticalAlignment="Top" Width="479" Background="#FFF2F2F2" />
    </Border>
</Grid>

这应该可以让您得到满意的收益（尽管您可能希望在全部4个项目上留出一定的利润）两侧，而不仅仅是2个...）

This should get you what you're after (though you may want to put a margin on all 4 sides, not just 2...)
