Occurs when a ListView is in virtual mode and the selection state of a range of items has changed.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

Public Event VirtualItemsSelectionRangeChanged As ListViewVirtualItemsSelectionRangeChangedEventHandler

If the ListView is not in virtual mode, the ItemSelectionChanged event will occur.

For more information about handling events, see Handling and Raising Events.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the VirtualItemsSelectionRangeChanged event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type ListView named ListView1. Then ensure that the event handler is associated with the VirtualItemsSelectionRangeChanged event.

Private Sub ListView1_VirtualItemsSelectionRangeChanged(sender as Object, e as ListViewVirtualItemsSelectionRangeChangedEventArgs) _ 
     Handles ListView1.VirtualItemsSelectionRangeChanged

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "EndIndex", e.EndIndex)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "IsSelected", e.IsSelected)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "StartIndex", e.StartIndex)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"VirtualItemsSelectionRangeChanged Event")

End Sub
