WPF 边框厚度仅底部..

Question

我正在尝试创建底部只有边框的 WPF 按钮，其余部分将隐藏。我尝试使用 borderthickness = "0,0,0,1"但它不起作用..这是我的代码..

<Button Background="Transparent" BorderThickness="0,0,0,1" BorderBrush="Transparent"  Width="235" Padding="5" FlowDirection="LeftToRight">
<StackPanel Orientation="Horizontal" Width="260">
<Image Source="Images/room-32.png" Height="20" Margin="30,0,8,0"/>
<TextBlock Width="200">Station Maintenance</TextBlock>
</StackPanel>
</Button>

Answer 1

这是因为 BorderBrush 设置为 Transparent。为其分配颜色。

<Button Background="Transparent" BorderThickness="0,0,0,1" BorderBrush="Black"  Width="235" Padding="5" FlowDirection="LeftToRight">
   <StackPanel Orientation="Horizontal" Width="260">
      <Image Source="Images/room-32.png" Height="20" Margin="30,0,8,0"/>
      <TextBlock Width="200">Station Maintenance</TextBlock>
   </StackPanel>
</Button>

所以，而不是

BorderBrush="Transparent"

使用

BorderBrush="Black" // Any color you would like

如果你想在你的 button 周围添加一个边框，甚至在 hover 等时都可见...那么在你的周围添加一个 border 元素 按钮。

  <Border BorderBrush="Black" BorderThickness="0,0,0,1">
      <Button Background="Transparent"
              Width="235"
              Padding="5"
              FlowDirection="LeftToRight">
          <StackPanel Orientation="Horizontal"
                      Width="260">
               <Image Source="Images/room-32.png"
                     Height="20"
                     Margin="30,0,8,0" />
               <TextBlock Width="200">Station Maintenance</TextBlock>
          </StackPanel>
      </Button>
  </Border>
