在网格视图卷轴末端加载更多项目 [英] Load more items on grid view scroll end

问题描述

我正在使用XAML / C＃开发Windows应用商店应用程序，并且我有一个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，更多的项目被添加到GridView中。我如何在最后抓取事件进行滚动？我尝试了很多方法，但没有任何工作......

更新：
我花了一个LOOOONG的时间和大量的例子想象我做错了什么。 ListView的工作，但GridView没有...
最后我注意到，GridView项目必须有一个宽度的高度，以便增量加载工作。

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...

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.

解决方案

See these examples to learn how to set ObservableCollection<T> that implements the ISupportIncrementalLoading interface.
