首先看一下可以进行绑定集合的控件属性，暂时我就不翻译了，因为翻译不好，还不如读英文呢。

Name	Description
ItemsSource	Points to the collection that has all the objects that will be shown in the list.
DisplayMemberPath	Identifies the property that will be used to creat the display text for each item.
ItemTemplate	Providers a data template that will be used to create the visual appearance of each item.This property acts as a far more powerful replacement for DisplayMemberPath.
ItemsPanel	Providers a template that will be used to create the layout container that holds all the items in the list.

这里你可能会想，什么类型的集合可以绑定到ItemsSource属性呢？告诉你，只需要实现IEnumerable就可以，但是，实现这个借口的集合是只读的。如果你想编辑这个集合，例如允许插入和删除，你需要更多的工作，后面我们会介绍。

显示并且编辑集合项

首先定义个数据库交互契约
