Wpf 为每个角使用不同的笔刷颜色设置边框样式
我已经在xaml中创建了一个静态资源来定义特定项的边框,但是我找不到一个好方法来为每一面定义唯一的颜色 xaml:Wpf 为每个角使用不同的笔刷颜色设置边框样式,wpf,xaml,colors,border,Wpf,Xaml,Colors,Border,我已经在xaml中创建了一个静态资源来定义特定项的边框,但是我找不到一个好方法来为每一面定义唯一的颜色 xaml: 静态资源: <Style x:Key="SidePanelBorder"> <Setter Property="Control.BorderBrush" Value="#FF363636" /> <Setter Property="Control.BorderThickness" Value="1" /> </Style
静态资源:
<Style x:Key="SidePanelBorder">
<Setter Property="Control.BorderBrush" Value="#FF363636" />
<Setter Property="Control.BorderThickness" Value="1" />
</Style>
但我想为边界的每一侧定义一种颜色,并最终定义不同的边界厚度
有什么好的技术可以做到这一点吗 如果不编写自己的控件或子类化边框,就很难做到这一点。看起来非常粗糙,但您可以在边框内定义边框,并使只有一面具有厚度。比如说
<Border BorderThickness="0,0,0,10" BorderBrush="Green">
<Border BorderThickness="0,0,10,0" BorderBrush="Blue">
<Grid>
<Button>Hello</Button>
</Grid>
</Border>
</Border>
你好
底部为绿色边框,右侧为蓝色边框。这不是Xaml中最漂亮的部分。你可以有一个DockPanel,可以在里面放4个边框,每个边框停靠在不同的一边。 比如:
……这里由你控制
如果您使用网格,您可以将边框重叠在另一个网格上,以实现相同的效果。只需设置要显示的边框颜色的边框厚度,并将其他边框厚度设置为0
<UserControl.Resources>
<Style x:Key="GreenBorder" TargetType="Border">
<Setter Property="BorderBrush" Value="Green" />
<Setter Property="BorderThickness" Value="1,1,1,0" />
</Style>
<Style x:Key="RedBorder" TargetType="Border">
<Setter Property="BorderBrush" Value="Red" />
<Setter Property="BorderThickness" Value="0,0,0,1" />
</Style>
</UserControl.Resources>
<Grid>

<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />

<Border Grid.Column="0" Grid.Row="0" Style="{StaticResource GreenBorder}">
<!-- Content goes here -->
</Border>
<Border Grid.Column="0" Grid.Row="0" Style="{StaticResource RedBorder}">
</Border>
</Grid>
这将为网格单元的左、上和右边框提供绿色边框,但为下边框提供红色边框。另一种解决方案使用一个边框和可视化笔刷,允许设置边框的拐角半径和边框厚度:

- 需要网格来防止三角形路径的尖端“穿过”边界
- Path.Name可用于数据绑定或设置代码隐藏的颜色
