public int VirtualListSize { get; set; }

Property Value

Type: System.Int32
The number of ListViewItem objects contained in the ListView when in virtual mode.

ExceptionCondition
ArgumentException

VirtualListSize is set to a value less than 0.

InvalidOperationException

VirtualMode is set to true, VirtualListSize is greater than 0, and RetrieveVirtualItem is not handled.

Getting or setting the VirtualListSize property when VirtualMode set to false will have no effect on the ListView.

If VirtualMode is set to true, and the VirtualListSize property is greater than 0, you must handle the RetrieveVirtualItem event, providing a valid ListViewItem.
