原有#xff1a;自己再做WPF页面设计后发现直接去查找页面多个控件嵌套情况下找不到指示灯#xff08;Button实现的#xff0c;详细可以看这篇文章 这里#xff09;#xff0c;具体看看来如何实现
加粗样式思路#xff1a;无论多级嵌套自己再做WPF页面设计后发现直接去查找页面多个控件嵌套情况下找不到指示灯Button实现的详细可以看这篇文章 这里具体看看来如何实现
加粗样式思路无论多级嵌套Grid都能找到指示灯 如何从TabControl 下的TabIten-StackPanel-StackPanel -GroupBox 一般都是一级一级的去找现在直接从Grid出发找为什么要从Grid出发找应为Grid有Children属性方便我们来直接使用
