Parameters: subfield  fieldname of a column of the main subform-datasource which has to be connected to the main datasource of the master form. masterfield  columnname of the main masterform-datasource which value has to be equal with the value of subfield. registerchange  if this class is part of a hk_presentation object (i.e. a form or a report) and registerchange is true, then the changes will be stored when the hk_presentation object is closed.
