所以我们面临一个问题，当我选择另一个过滤器之后的过滤器然后我没有得到我的listview中的先前过滤数据..我的意思是第二个过滤器适用于一个新的列表....所有三个过滤器单独工作很好，但在链接工作时，所有过滤器总是在新的列表上工作，在之前的过滤列表... 伙计们请帮帮我.... 请给我一个正确的逻辑代码来解决这个问题....

您可以查看这是否符合您的需求：http://dotnetexplorer.blog.com/2011/04/07/wpf-itemscontrol-generic-staticreal-time-filter-custom-control-presentation/
这是一个多重过滤器组件，可以处理最常见的.net集合并将其自身附加到任何WPF ItemsControl
唯一的缺点是这是一个站在ItemsControl外面的组件......
