问题描述

In keyboard navigation, when a button is selected, it has a dashed border. How to change its color?

推荐答案

我相信你正在寻找的是 FocusVisualStyle 。如果设置为null，则可以隐藏虚线边框。在你的情况，你想改变颜色。你会做什么是创建一个新样式，并将其应用到 FocusVisualStyle 。

I believe what you are looking for is the FocusVisualStyle. If you set this to null, you can hide the dashed border. In your case, you want to change the color. What you would do would be to create a new style and apply it to the FocusVisualStyle.

下面是一个MSDN文章将告诉您如何做到这一点：

Here is an MSDN article that shows you how to do this:

基本code他们列出如下：

The basic code they list is as follows:

<Page.Resources>
  <Style x:Key="MyFocusVisual">
    <Setter Property="Control.Template">
      <Setter.Value>
        <ControlTemplate>
          <Rectangle Margin="-2" StrokeThickness="1" Stroke="Red" StrokeDashArray="1 2"/>
        </ControlTemplate>
      </Setter.Value>
    </Setter>
  </Style>
</Page.Resources>
<StackPanel Background="Ivory" Orientation="Horizontal">
  <Canvas Width="10"/>
  <Button Width="100" Height="30" FocusVisualStyle="{DynamicResource MyFocusVisual}">
    Focus Here</Button>
  <Canvas Width="100"/>
  <Button Width="100" Height="30" FocusVisualStyle="{DynamicResource MyFocusVisual}">
    Focus Here</Button>
</StackPanel>
