get old / new value of changed entity member

Hello everybody,

I was looking for some method / function by means of which i can get new values of a changed entity member,

as i already can get old values of changed members by doing this...

IEnumerable<string> modifiedFields = _context.GetMemberNames(_​entityName, Telerik.OpenAccess.ObjectState.Dirty);
foreach (var array in modifiedFields)
         MessageBox.Show("OLD = " + _context.GetOriginalValue<string>(_securityData, array) );

how to get new values ?
