推荐答案
有一对夫妇的解决方案 - 一切取决于您要进行的工作。另外，我建议你没有一个更多按钮，如果你能帮助它 - 这是不是最好的用户交互。选项2要给你最好的体验。
There are a couple of solutions -- all depending on the work that you want to undertake. Also, I would suggest that you don't have a "More" button if you can help it -- it's not the best user interaction. Option 2 is going to give you the best experience.
选项1
使用 WinJS.Binding.List 作为数据源 - 使用此，你可以操纵它像一个JavaScript 阵列（例如推， POP等）。当您添加和放大器;从列表中删除项目，列表视图将反应这些变化。
Use WinJS.Binding.List as your data source -- using this you can manipulate it like a JavaScript Array (e.g. push, pop etc). As you add & remove items from the list, the list view will react to those changes.

选项2
创建VirtualDataSource推导是密切注意在其中您可以要求你的数据，并能提供一个一致的界面到ListView的方式。这使得使用者介面是完全的灵活性，以它的布局，并且要求足够的数据来满足的可用空间，而虚拟化的UI元素（优于存储器/性能），和数据（确保只有数据的需要的由用户请求
Create a VirtualDataSource derivation that is intimately aware of the ways in which you can request your data, and can offer up a consistent interface to the ListView. This enables your UI to be completely flexible to it's layout, and request enough data to satisfy the available space, while virtualizing the UI elements (better memory/performance), and the data (ensuring only the data needed by the user is requested.
全部样例。
