通过虚拟模式在ListView的所有元素循环 [英] Loop through all elements in a ListView in virtual mode

问题描述

我有一个创建一个从列表视图的PDF报告报告模块。

I have a reporting module which creates PDF reports from ListViews.

现在，我在虚拟模式的ListView，所以我不能遍历所有的项目集合。

Now, I have a ListView in Virtual mode and therefore I cannot loop over the Items collection.

我如何遍历从报告模块列表视图中的所有元素？

How do I loop over all elements in the list view from the reporting module?

我可以得到 VirtualListSize 属性，所以我知道有多少元素有在列表中。
我可以以某种方式调用 RetreiveVirtualItem 明确？

I can get the VirtualListSize property, so I know how many elements there are in the list. Could I somehow call the RetreiveVirtualItem explicitly?

报表模块没有关于在ListView垫层名单知识。

The Reporting module has no knowledge about the underlaying list in the ListView.

推荐答案

在一个虚拟的ListView，你不能重复的项目，但你仍然可以通过它们的索引来访问它们

In a virtual ListView, you cannot iterate the Items, but you can still access them by their index:

for (int i = 0; i <  theVirtualListView.VirtualListSize; i++) {
    this.DoSomething(theVirtualListView.Items[i]);
}
