The ListView control raises the ItemDeleting event when a Delete button is clicked or the DeleteItem method is called, but before the ListView control deletes the item. (A Delete button is one whose CommandName property is set to "Delete".) This enables you to provide an event-handling method that performs a custom routine whenever this event occurs, such as canceling the delete operation.

A ListViewDeleteEventArgs object is passed to the event-handling method, which enables you to determine the index of the item that is being deleted. You can also cancel the delete operation. To do so, set the Cancel property of the ListViewDeleteEventArgs object to true. If necessary, you can also work with the Keys and Values collections before the values are passed to the data source.

For a list of initial property values for an instance of ListViewDeleteEventArgs, see the ListViewDeleteEventArgs constructor.

The following example shows how to use the ListViewDeleteEventArgs object to cancel the delete operation if the user tries to remove the last item from a ListView control.
