Remarks

The ListView control raises the ItemDeleted event when a Delete button in the control is clicked or the DeleteItem method is called, but after the ListView control deletes the item. (A Delete button is a button 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 checking the results of a delete operation.

A ListViewDeletedEventArgs object is passed to the event-handling method. This object enables you to determine the number of items affected and any exceptions that might have occurred. To determine the number of items that were affected by the delete operation, use the AffectedRows property. To determine whether any exceptions occurred, use the Exception property. You can indicate whether you have handled the exception in the event-handling method by setting the ExceptionHandled property.

Note

If an exception occurs during the delete operation and the ExceptionHandled property is set to false, the ListView control re-throws the exception.

To access the key fields of the deleted item, use the Keys property. To access non-key fields of the deleted item, use the Values property. For a list of initial property values for an instance of the ListViewDeletedEventArgs class, see the ListViewDeletedEventArgs constructor.
