When a ListView object is in virtual mode, it creates ListViewItem objects dynamically instead of using the Items collection. This event is raised when the object must create a ListViewItem object. A handler for this event should create the appropriate ListViewItem or retrieve it from the cache, and pass it back by way of the Item property.
The following code example demonstrates a handler for this event. In this example, listView1 needs each ListViewItem to display the square of its index. This code example is part of a larger example provided for the VirtualMode property.
