推荐答案

基本上，虚拟列表控件使您可以创建一个列表框，其中包含很多项目，但只将一部分数据加载到内存中.当用户滚动浏览列表并耗尽内存中的项目时，列表控件将加载更多数据:

Basically the virtual list control lets you have a listbox with a very large number of items in it but only load a subset of the data into memory. As the user scrolls through the list and exhausts the items in memory then the list control loads more data:

.NET版本是通过ListView控件的'VirtualMode'属性实现的.设置为true时，它将充当虚拟列表.您的代码处理"RetrieveVirtualItem"事件，以在虚拟列表的项目用尽时将更多数据加载到列表视图中:

The .NET version is implemented with the 'VirtualMode' property of the ListView control. When this is set to true it will act as a virtual list. Your code handles the "RetrieveVirtualItem" event to load more data into the list view as the virtual list's items are exhausted:
