Examples

The following code example demonstrates the use of this type. 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 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 void ListView1_VirtualItemsSelectionRangeChanged(Object sender, ListViewVirtualItemsSelectionRangeChangedEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "EndIndex", e.EndIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "IsSelected", e.IsSelected );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "StartIndex", e.StartIndex );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "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
