WPF列表框重复项 [英] WPF Listbox duplicate items

问题描述

我一直在到处寻找解决方案，但最终承认失败.请有人帮我.

我有一个绑定到可观察集合的列表框.当在普通视图中打开窗口时，列表很好，并且集合中的每个项目都在其中.如果我随后使用IcollectionView对项目进行排序或分组，则可以正常工作，除非我得到三个 每一项和其中两项都会引发错误，而一项选择还可以.

我已经阅读了书籍，论坛和教程，而我尝试过的所有事情都引发了同样的问题.我正在使用Visual Express 2010 C#

任何帮助或建议将不胜感激.

谢谢

Hi ,

I have been looking everywhere for a solution but have finally admitted defeat. Please could someone help me. 

I have a Listbox bound to an observable collection .When the window opens in a normal view the list is fine and there is on of each item from my collection. If I then use IcollectionView to sort or group my items it works correctly except I get three of each item and two of them throw an error and one selects okay.

I have read books, forums and tutorials and everything I have tried throws the same problem. I am using Visual Express 2010 C#

any help or advice would be very much appreiciated.

Thank you
