Remarks
A list box editor’s list items can be deleted by using the server (ListEditItemCollection.Remove, StateManagedCollectionBase.Clear or client (ASPxClientListBox.RemoveItem, ASPxClientListBox.ClearItems) methods. Each time a list item is going to be deleted from the editor’s ASPxListEdit.Items collection, the ItemDeleting event occurs, allowing you to cancel item deletion. To cancel the delete operation, set the event parameter’s Cancel property to true.
After a list item has been deleted, the ASPxAutoCompleteBoxBase.ItemDeleted event is raised.
