C# 将设置绑定到一组单选按钮

我这里有一种恼人的情景。 在我的WPF GUI中，我声明了一些单选按钮，我希望在GUI加载时检查正确的单选按钮

XAML：

---

但是CustomRadioButton IsChecked属性不会绑定到它，因为我需要创建DependencyProperty，我不知道如何对DependencyProperty执行相同的操作。请提供帮助。

如果您想使用绑定进行此操作，请尝试此操作

xaml

如果您像我在这里看到的那样大量使用这种绑定，那么为了减少xaml代码，我们可以这样做，如下所示

xaml

转换器

单击“我的说明”中的WPF GUI链接。所有内容都是链接的。很遗憾，我们不是来查看您的源代码的。如果您需要帮助，您需要在这里为我们提供一个更具体的示例。好的，补充了所有内容，现在应该更清楚了。很抱歉没有从一开始就这么做。我现在已经尝试了两种方法，但都不起作用。我不得不稍微修改RadioButtonBinding函数，因为我不能在XAML中将“HonkySettings.Default.TrayiConBehavior”作为参数写入。我删除了RadioButtonBinding构造函数上的参数，并将HonkySettings.Default.TrayIconBehavior设置直接添加到第一个新绑定（）中。使用这种方式，在按下RadioButton时无法转换回内容值，因为ConvertBack函数中的值是布尔值。
