WPF Expander Style 控件样式自定义控件自定义属性

下载连接 https://download.csdn.net/download/sinat_30224769/12366122

Wpf中使用 Expander 的样式，如果需要绑定自己的属性可以继承Expander 并添加自己需要的属性，如果属性较多可以只绑定一个类，注意增加通知。最后在样式中使用TempleteBinding 来帮顶自己设置的值，不要忘了要设置Templete的 X：TargetType 继承的类

样式资源DefaultStyleDictionary.xaml 我这里只改了一个Down情况的因为只用到这一种，如果需要对应其他方向的，自己照葫芦画瓢
