自定义单选按钮UWP

新手编码器

我正在尝试自定义单选按钮，以使选中时外部椭圆为黑色，内部圆圈填充为黑色。另外，我还想将所选项目的字体粗细更改为粗体。目前，我的外部椭圆为黑色，内部圆圈为黑色，但是当我将鼠标悬停在其上时，我可以看到它变为按钮的默认行为。我的代码如下：

    <Style x:Key="RadioButtonStyle1" TargetType="RadioButton">
        <Setter Property="Background" Value="{ThemeResource RadioButtonBackground}"/>
        <Setter Property="Foreground" Value="{ThemeResource RadioButtonForeground}"/>

        <Setter Property="Padding" Value="8,6,0,0"/>
        <Setter Property="HorizontalAlignment" Value="Left"/>
        <Setter Property="VerticalAlignment" Value="Center"/>

当我将鼠标悬停在单选按钮上时，如何确保保留设置的属性，以及如何使所选选项显示为粗体。

我还想将所选项目的字体粗细更改为粗体。

如果要在选择时编辑内容字体粗细，可以将其添加DiscreteObjectKeyFrame到选中的VisualState中，如下所示。

<VisualState x:Name="Checked">
    <Storyboard>
        <DoubleAnimation
            Storyboard.TargetName="CheckGlyph"
            Storyboard.TargetProperty="Opacity"
            To="1"
            Duration="0" />
        <DoubleAnimation
            Storyboard.TargetName="OuterEllipse"
            Storyboard.TargetProperty="Opacity"
            To="0"
            Duration="0" />
        <DoubleAnimation
            Storyboard.TargetName="CheckOuterEllipse"
            Storyboard.TargetProperty="Opacity"
            To="1"
            Duration="0" />
        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ContentPresenter" Storyboard.TargetProperty="FontWeight">
            <DiscreteObjectKeyFrame KeyTime="0" Value="Bold" />
        </ObjectAnimationUsingKeyFrames>
    </Storyboard>
</VisualState>
