1、xaml的Resources中添加一个FrameworkElement的代理
2、用一个隐藏的ContentControl绑定FrameworkElement代理
3、用代理做Visibility的数据源
BindingProxy类
public class BindingProxy:Freezable
{
protected override Freezable CreateInstanceCore()
{
return new BindingProxy();
//throw new NotImplementedException();
}
{
get { return (object)GetValue(DataProperty); }
set { SetValue(DataProperty, value); }
}
}
