在网格视图滚动端加载更多项目 [英] Load more items on grid view scroll end

问题描述

我正在用 XAML/C# 开发 Windows 应用商店应用程序，我有一个 GridView，一次显示 12 个项目 (3 x 4).我需要做的是，一旦用户滚动到最后，就会向 GridView 添加更多项目.我如何捕捉最后滚动的事件?我尝试了很多方法，但没有任何效果...

I am developing a Windows Store Application in XAML/C# and I have a GridView displaying 12 items at a time (3 x 4). What I need to do is once the user scrolls to the end, more items are added to the GridView. How do I catch the event for scrolling at end?? I tried many approaches, but nothing worked...

更新:我花了很长时间和很多例子来弄清楚我做错了什么.ListView 有效，但 GridView 没有...最后我注意到 GridView 项目必须有一个宽度高度才能使增量加载工作.

UPDATE: It took me a LOOOONG time and lots of examples to figure what I was doing wrong. ListView worked, but GridView didn't... Finally I noticed that the GridView items must have a width height in order for incremental loading to work.
