I am not sure what you mean by "that don't get the value from database by value field"
Do you mean that your drop-down list is not bound to a database table?
See: http://developers.sun.com/jscreator/learning/tutorials/2/listbox_components.htm l
Do you mean that you want to get a different value from the database record that was selected? Then here is one way to do it: It finds the record for the corresponding id. Once you get the record you can get any other value from that record:
personDataProvider.setCursorRow(
personDataProvider.findFirst(
"PERSON.PERSONID", personIdDD.getSelected()));
Here are some sample programs to give you ideas:
