hi,
Wish to know whether following thing is possible in forms 9i.
need to display records from database and option button with each row. My pbm is at a single point of time, all options are selected. I am unable to deselect that...Need to write some code for this or is there any automatic way for doing this?
I worked with check box. working fine. Since, user has to be restricted with one selection, I need to work with option button.
Pl help.
Regards,
Priya

Thanks David for ur reply..i am explaining my pbm in detail below
At a single point of time, only one rec shd be selected. Based on selection, I will perform an action. But using radio group, I am unable to do this...
For eg, there are 5 records
<radio1> <rec1>
<radio2> <rec2>
<radio3> <rec3>
<radio4> <rec4>
<radio5> <rec5>
at a point of time, i am selecting 3rd option...[only one option is allowed..that z y i am going for radio button] after selection, i will press push button...is it possible...and i need to map the record according to selection .

Okay ... I think what you are saying is you want to display 5 rows from a table of many rows and then select one and only one of these entries. Then press a button to use the data in this row to do something.
Assuming I am right. Place a check-box (non-database) in your multi-row block and display it to the left of your fields. In the When-Checkbox-Changed either turn off the capability of changing the other check-boxes [Set-Item-Property disable, Set-Item-Instance-Property enable] or loop through all the records and turn off any check-box that has been turned on [store :system.trigger_record or get_block_property(current_record), first_record, loop until :system.last_record, if checkbox 'set' then 'unset'; exit loop if you wish otherwise run to end of loop; finally go_record(stored_row_num).
To get the screen to match exactly the first screen row placement you will need to know the row number of the top line, then go to top_line, then go to current_line. Try for yourself, it isn't too difficult.
David
Upd: You can't disable an item and then enable an item-instance. You could just set a :global that 'checkbox has been set' and test for it in a when-new-record-instance and turn the field off for that line and move to the next field.

David,
C...i think i did not exp my pbm clearly.
For each rec, there will be one radio group right?
if i select particular rec, other options in other records should not be selected. it is getting selected because i placed radio group once while creating data block..it is a non-db item.
i planned to capture the property of radio button selected at runtime...no clues for me

That's one of the problems of a radio group, how to turn it 'off'. Either add another element to the radio group called 'off' which sets the value back to the default, or you could have both a check-box and the radio group on each record. When the radio group has an element selected you can turn the check-box 'on', then if they want to turn the radio group 'off' they unselect the check-box.
