除非我在spriteToggleButton中重复该过程，但我已在其中注册了依赖项属性，因此datacontext可能缺少一个步骤。Debug output window在出现绑定问题时会使用它来大叫。你检查过了吗？奇怪的是，你对内容使用TemplateBinding，而对精灵使用简单的绑定。DataContext设置是否正确？'Selected'属性未在'Project.Quike+Answer'项目.Quike+Answer'中找到找不到highlightedSprite的属性。。etc@Jan如何设置数据上下文？像这样的DataContext={Binding.}这是什么意思？如果你没有立即提供完整的信息，很难回答。也许是因为绑定终于开始工作了。还要检查TargetType，也许这就是问题所在。这是我的最后一个回复，这是一个一般性的评论：读取调试输出。阅读异常详细信息。在崩溃时检查按钮的属性。分析所有这些信息，你就会得到答案。
