在ListView的WP8增量加载 [英] Incremental Loading in ListView WP8

问题描述

我看了一下如何做增量加载，当我们滚动到列表视图的底部，但如何实现延迟加载，当我们滚动到列表顶部的文章。我想更多的项目时，用户到达顶部添加到列表的顶部。有什么办法，我们可以做到这一点。

I have read the articles about how to do incremental loading when we scroll to bottom of the list view, but how to achieve lazy loading when we scroll to top of the list. I want to add more items to the top of the list when the user reaches the top. Is there any way we can achieve this.
