The BeforeLabelEdit event occurs when the user starts modifying the text for an item. If the event handler cancels this event, the user cannot edit the text. You can use this event to prevent the user from editing specific items in the ListView control. If the LabelEdit property of the ListView control is set to false, the BeforeLabelEdit event is not raised; all user attempts to edit item labels are automatically rejected.
The following code example demonstrates handling the BeforeLabelEdit event and using the LabelEditEventArgs.Item and LabelEditEventArgs.CancelEdit properties. To run the example, paste the following code into a form that contains a ListView control named ListView1 and populated with at least three items. Ensure the event handler in the example is associated with its event.
