本文介绍了我怎样才能在C＃中选择项目（S）和事件的ListView与Caliburn.Micro？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我写了一个程序与MVVM（C＃）和XAML使用Caliburn.Micro库，我怎么能：
- 获得全部所选的项目（不仅是一个项目）？
- 选择得到改变事件？
- 排序点击标题列的项目？
任何帮助将是AP preciated。

解决方案
您必须对这些事件挂钩到一个命令，然后在视图模型处理它们。
不使用Caliburn.Micro但也应该是EventToCommand绑定的概念。我快速搜索发现下面的链接。

心连心
I wrote a program with MVVM (C#) and XAML using Caliburn.Micro library, how can i:
- get all selected items (not only one item)?
- get selected change event?
- sort items by clicking header columns?
Any help would be appreciated.

解决方案
You have to hook up these events to a command and process them in the viewmodel.
Not using Caliburn.Micro but there should also be a concept for EventToCommand Binding. I quick search revealed the following links.
