Question

我正在为radiobutton创建一个样式，并在单击时更改radiobutton的颜色。但是，我想这样，当你mouseover放射性按钮时，它也会改变颜色。我已经实现了基础知识，但是当已选择了无线电按钮（因此具有不同的颜色）时，如果它获得mouseover，则颜色会更改为该新颜色，并且当mouseover完成时（鼠标离开它，颜色变回原始的未选择的颜色。

有没有办法让它知道什么时候点击它才能找到正确的颜色？（TargetName Border只是一个Border类）

<Style x:Key="MyRadioButton" TargetType="{x:Type RadioButton}">

Answer 1

使用此Style，并将两个差异RadioButton置于测试Unchecked状态：

<Style TargetType="{x:Type RadioButton}">
            <Setter Property="SnapsToDevicePixels" Value="true" />
            <Setter Property="FocusVisualStyle" Value="{DynamicResource RadioButtonFocusVisual}" />
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type RadioButton}">
                        <BulletDecorator Background="Transparent">

                            <BulletDecorator.Bullet>
