Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
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.
For more information about handling events, see Handling and Raising Events.
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.
