为每个角落设置不同画笔颜色的边框

问题描述

我已经创建了一个静态资源定义在我的xaml中的特定项目的边框，但我找不到一个很好的方法来定义每一侧的唯一颜色！

I have created a static resource defining the border of a specific item in my xaml, but I can't find a good way to define a unique color for each side!

xaml：

<Border Style="{StaticResource SidePanelBorder}">
        <!-- rest of the xaml -->
</Border>

StaticResource：

StaticResource:

<Style x:Key="SidePanelBorder">
    <Setter Property="Control.BorderBrush" Value="#FF363636" />
    <Setter Property="Control.BorderThickness" Value="1" />
</Style>

但是我想为边框的每一边定义一种颜色， 。

But I want to define one color for each side of the border, and eventually also a different Border thickness.

有什么好的技术吗？

推荐答案

看起来很黑，但你可以在边框内定义边框，只有一边有厚度。例如

Seems very hacky, but you could define borders within borders, and make only 1 side have a thickness. For example

<Border BorderThickness="0,0,0,10" BorderBrush="Green">
    <Border BorderThickness="0,0,10,0" BorderBrush="Blue">
        <Grid>
            <Button>Hello</Button>
        </Grid>
    </Border>
</Border>

将在底部给出一个绿色边框，在右边给出一个蓝色边框。不是最漂亮的Xaml。

would give a green border on the bottom and a blue border to the right. Isn't the prettiest piece of Xaml though.
