如何检测到 LongListSelector 的结尾?(WP8) [英] How to detect that the end of LongListSelector is reached? (WP8)

问题描述

我需要创建以下逻辑.例如，LongListSelector 最初包含 10 个项目.当用户将其滚动到结尾时，必须加载另外 10 个项目并将其添加到此 LongListSelector.再说一次，如果用户到达列表的末尾，则必须再添加 10 个项目.

I need to create the following logic. For example, LongListSelector contains 10 items initially. When user scrolled it to end, another 10 items must be loaded and added to this LongListSelector. Then again, if user reached the end of the list, 10 more items must be added.

我也预测可能存在以下问题.列表结束的事件必须只触发一次，直到加载新的 10 个项目.在触发新的列表结束事件"之前，我必须防止多次触发并让新项目被加载.

I also predict that there might be the following problem. The event of the list's end must be triggered only once, until new 10 items will be loaded. I must prevent multiple triggering and let the new items to be loaded, before new "End of List Event" will be triggered.

那么，如何制作呢?首先，我需要知道，如何检测到了 LongListSelector 的末尾?

So, how to make it? First of all, I need to know, how to detect that the end of the LongListSelector is reached?
