By default, the DataSecurityMode property is set to the Default value. This means that a list editor allows adding new list items via client code and synchronizes modifications to this list with the server ASPxAutoCompleteBoxBase.Items collection if the ASPxAutoCompleteBoxBase.EnableSynchronization property is enabled.
