这是我用于单选按钮的自定义样式。概念是在选中和未选中状态之间翻转前景色和背景色。一切正常，直到我将鼠标移到选中的按钮上并将其移出。前景切换回原色。
澄清这一点，这是我认为正在发生的事情。
- 单击按钮时，选中状态变为活动状态。
- 当您将指针移到上方时，PointerOver 状态变为活动状态并将前景更改为 WhiteTextAndIcons 颜色。
- 当指针移出时，前景返回默认值，即 PrimaryColor，因此它与背景匹配。
我需要的是，如果检查了状态，那么当指针移入或移出时，前景不应默认返回。这可以通过风格实现吗？
这是我正在使用的解决方法，但我想知道我在这里做错了什么。
解决方法：
private void MainPage_PointerExited(object sender, PointerRoutedEventArgs e)
{
if(sender is RadioButton)
{
var radio = sender as RadioButton;
if(radio.IsChecked.HasValue && radio.IsChecked.Value)
{
radio.IsChecked = false;
radio.IsChecked = true;
}
}
}
