Drop-Down Boxes

Question

I have created a form using the PL/SQL Toolkit. I have 2 drop-down boxes.
Let's say the options listed in drop-down box 1 are Company Names and the options in drop-down box 2 are Employee Names.
The thing that I want to happen is this: When I choose a Company from drop-down box 1, drop-down box 2 will change such as the Employee Names that are listed are those who work for the Company that I chose in drop-down box 1. How is this possible?

Answer 1

You can do it this way :
Hope you have a table for company names and emp names.
Populate the forst drop dpwn box with the company names, populate it dynamically instead using POPULATE_LIST built-in.
WHEN-NEW-FORM-INSTANCE-TRIGGER:
DECLARE
rg_name VARCHAR2(1000);
BEGIN
rg_name := 'SELECT COMPANY_NAME FROM TABLE_NAME';
POPULATE_LIST('company_list_name', rg_name);
END;
WHEN-VALIDATE-ITEM or POST-CHANGE trigger of the company list_item :
DECLARE
rg_name VARCHAR2(1000);
BEGIN
rg_name := 'SELECT EMPLOYEE_NAME FROM TABLE_NAME WHERE COMPANY_NAME = :COMPANY_LIST';
POPULATE_LIST('emp_list_name', rg_name);
END;
Hope this helps you.
