C# 边界笔刷不可见

我有三个单选按钮。通常情况下，radioButton中的

边框笔刷不可见，但其属性不为null。当我单击radioButton（单选按钮）时，中央单选按钮将可见，但
边框笔刷
不可见

为什么边界笔刷不可见

<RadioButton Content="Low" 
             Tag="Low" 
             Grid.Row="1"
             BorderBrush="{StaticResource LowPrioritySolidColorBrush}"
             Checked="OnPriorityButtonChecked"
             FontSize="17"
             Visibility="Visible"
             Margin="0,15,0,0"/>
<RadioButton Grid.Column="1" 
             Margin="0,15,0,0"
             Grid.Row="1"
             Content="Medium" 
             Tag="Medium" 
             Visibility="Visible"
             BorderBrush="{StaticResource MediumPrioritySolidColorBrush}"
             Checked="OnPriorityButtonChecked"
             FontSize="17"/>
<RadioButton Grid.Column="2" 
             Margin="20,15,0,0"
             Grid.Row="1"
             Content="High"
             Tag="High" 
             Visibility="Visible"
             BorderBrush="{StaticResource HighPrioritySolidColorBrush}" 
             Checked="OnPriorityButtonChecked"
             FontSize="17"/>




这是UWP中
单选按钮的默认外观：


默认情况下，“复选框”的轮廓为黑色，选中按钮时，颜色将更改为用户的强调色。里面的圆点也是黑色的。但是，在您的情况下，
单选按钮
看起来非常不同，内部有彩色圆点，没有轮廓，因此必须对其应用自定义的
样式
。尝试在您的解决方案中搜索
TargetType=“RadioButton”
以找到它。
单选按钮不必直接具有
样式
，但只要不定义
x:Key
就可以定义针对它们的
样式

将
BorderBrush
和
BorderThickness
应用于默认样式时，结果如下所示：


我猜这不是你想要的：-）。为了实现您的目标，您必须声明您自己的自定义样式，该样式将使用
BorderBrush
作为轮廓的源颜色：

您是否定义了边框宽度？边框可能与背景颜色相同？您的意思是边框厚度？不可能。它们有3种不同的颜色。您必须在此处发布单选按钮样式的XAML，因为问题几乎肯定就在其中。您是否定义了边框宽度？边框可能与背景颜色相同？您的意思是边框厚度？不可能。它们有3种不同的颜色。你必须在这里发布你的单选按钮样式的XAML，因为问题几乎肯定就在它里面。我有相同的代码。上次我的代码是工作。我没有改变任何事情。但现在它不起作用了。因此我需要你的帮助。有一点相切：值得指出的是，虽然这是一个很好的结果，但它不是很好的UI。一个色盲的人不能区分不同的颜色，所以这个人会迷失方向。一般来说，当你想用颜色来区分时，你也应该试着用其他东西来区分——形状、图标、下划线等等，这样你就可以了解每个项目对每个人的重要性。总而言之，+1代表解决方案；干得好。：）@当然，您还必须使用

将样式应用于单选按钮。我在回答中添加了一个例子。@AriRoth你是对的，但在本例中，每个单选按钮都有一个标签，它确实逐字说明了优先级，因此应该是好的：-）。@MartinZikmund True！在这种情况下，文本将涵盖它。我只是想指出，一般来说，简单的颜色是不够的视觉分隔（除了阴影——例如，较深/较浅的灰色阴影通常是可以的）。就像我说的，切线。：）我有相同的密码。上次我的代码是工作。我没有改变任何事情。但现在它不起作用了。因此我需要你的帮助。有一点相切：值得指出的是，虽然这是一个很好的结果，但它不是很好的UI。一个色盲的人不能区分不同的颜色，所以这个人会迷失方向。一般来说，当你想用颜色来区分时，你也应该试着用其他东西来区分——形状、图标、下划线等等，这样你就可以了解每个项目对每个人的重要性。总而言之，+1代表解决方案；干得好。：）@当然，您还必须使用
