Question : Oracle forms 10g

Dear Expert,
i have a radio button and it has 3 values

if the button value = 'A1' then i have to populate the list item
with some set of values.and if it is 'A2' then other set of values then if it is 'A3' then i have to populate with other set of value.
The list item should dynamically populate the values.
Please help me.

Answer : Oracle forms 10g

The WHEN-RADIO-CHANGED trigger can be used to determine when the radio group value has changed. See the attached sample form for an example of how to change the list values, which I have coded using a program unit called build_list as follows:

Note: In my example, the build_list procedure takes a parameter from the radio group and it is this parameter that controls what data the select statement will retrieve.

Due to the restrictions on file name extensions enforced by Experts Exchange, the attached file has the extension jpg. This needs to be changed to fmb to give LIST.fmb. The form can then be opened in Oracle Forms Builder.
The form is based on the emp and dept demo tables provided by Oracle.
