C# 如何在不破坏控件模板功能的情况下绑定到属性？

我制作了一个控件模板，它的目标类型是if按钮。 它的两个事件触发器属于IsEnable和IsNoteable属性。当控制模板启用时，我将不透明度设置为100%，当不启用时，我将不透明度设置为40%

在我的GUI窗口中，我定义了一个新按钮，如下所示：

<Button x:Name="JoinB" 
        IsEnabled="{Binding Path=GroupStatus,Converter={StaticResource EnableConverter}}"  
        Template="{DynamicResource JoinButtonStyle}" />

---

}

而不是像您当前那样为启用/禁用状态使用两个不同的触发器

将它们与进入/退出合并为一个触发器

你能提供你的模板代码吗？我写了一个转换器和一个控制模板，发现不透明度更新正确。请张贴JoinButtonStyle的代码以及EnableConverter；在主要问题中添加了我的代码绑定时，是否在Convert方法中设置了断点以查看是否调用了它以及使用了哪些参数？是的，我使用断点进行了检查，结果良好。根据枚举返回true或false

<Button x:Name="JoinB" IsEnabled="false"  
        Template="{DynamicResource JoinButtonStyle}" />
