Getting and Setting On-Screen Values

You can use getter and setter methods to retrieve and set the values of fields on the current page when a user clicks a button. For all fields, language dependent code (LDC) values are retrieved, however for picklists, there are also additional getter and setter methods to retrieve and set language independent code (LIC) values. For information about these methods, see Methods for the Field Object and Getting and Setting LIC Values of Picklists.
