文本框周围的部分边框
Partial border around Textbox
在我 phone 上的 Spotify 应用程序的屏幕截图中，您可以看到他们在左下角和右下角做了一些看起来像部分边框的事情。我找不到任何具体的 属性 来模拟，所以有人可以向我解释他们是怎么做到的吗？
我试过使用边界半径，但除非我做错了什么，否则我认为这不是那么简单。他们只是在它下面有一个自定义形状吗？
您可以使用 LinearGradientBrush 和四个 GradientStop 点来实现：
<TextBox Background="WhiteSmoke" BorderThickness="3" Height="50" Width="200" VerticalAlignment="Center" HorizontalAlignment="Center">
<TextBox.BorderBrush>
<LinearGradientBrush EndPoint="1,1" StartPoint="1,0">
<GradientStop Color="White" Offset="0"/>
<GradientStop Color="White" Offset="0.75"/>
<GradientStop Color="Green" Offset="0.75"/>
<GradientStop Color="Green" Offset="1"/>
</LinearGradientBrush>
</TextBox.BorderBrush>
</TextBox>
这里是结果
更好的方法是重新设置 TextBox 的样式，使左右两个 Rectangle 位于侧面，一个位于底部，以模仿半边框外观。
<Rectangle x:Name="BottomLine" Grid.ColumnSpan="2" Grid.Row="1" Grid.RowSpan="1" VerticalAlignment="Bottom" Height="2" Fill="{TemplateBinding BorderBrush}" />
<Rectangle x:Name="LeftVerticalLine" HorizontalAlignment="Left" Height="4" Margin="0,0,0,2" Grid.Row="1" Stretch="Fill" UseLayoutRounding="True" VerticalAlignment="Bottom" Width="2" RenderTransformOrigin="0.5,1" Fill="{TemplateBinding BorderBrush}">
<Rectangle.RenderTransform>
<CompositeTransform />
</Rectangle.RenderTransform>
</Rectangle>
<Rectangle x:Name="RightVerticalLine" HorizontalAlignment="Right" Height="4" Margin="0,0,0,2" Grid.Row="1" Stretch="Fill" UseLayoutRounding="True" VerticalAlignment="Bottom" Width="2" RenderTransformOrigin="0.5,1" Grid.ColumnSpan="2" Fill="{TemplateBinding BorderBrush}">
<Rectangle.RenderTransform>
<CompositeTransform />
</Rectangle.RenderTransform>
</Rectangle>
为什么更好？因为它们现在是 TextBox 模板的组件，所以您可以将动画应用于视觉状态以获得更好的用户体验。
比如我想在TextBox处于Focused模式时，用ScaleTransform放大左右Rectangle，告诉用户他们当前正在与此控件进行交互。
这是完整的样式。 :)
