I am using Oracle Forms 6i.
I have a non database data block with some textbox and Listbox. This data block is used to display value from database and insert value in database. Data is fetched from database and it is assigned to datablock item through code. There are say 10 items displayed at a time in the datablock.
Requirement is to make the Listbox editable only when there is no data in one corresponding textbox column, and if there is data in that column then the List box should not be editable.
Can anyone please help how to achieve this in Oracle Forms 6i?
