Hi i have a multirecords form and i made a main checkbox which will select/ unselect all records
CODE:

begin
    go_block('ATTENDANCE');
    FIRST_RECORD;
    if :MAIN_CHECKBOX.MAIN_CHECK_BOX = 'Y' then
        loop                     
            :ATTENDANCE.SIGGNED := 'Y' ;
            EXIT WHEN :SYSTEM.LAST_RECORD = 'TRUE';
            NEXT_RECORD;
        end loop;
    else
        loop                     
            :ATTENDANCE.SIGGNED := 'N' ;
            EXIT WHEN :SYSTEM.LAST_RECORD = 'TRUE';
            NEXT_RECORD;
        end loop;
    end if;
    FIRST_RECORD;
end;

now there is a button that i should be hit after selection to disable "lock" selected records and some selected item (i.e: main checkbox)
i used:

SET_ITEM_PROPERTY('MAIN_CHECKBOX.MAIN_CHECK_BOX', UPDATE_ALLOWED,PROPERTY_FALSE)
SET_ITEM_PROPERTY('MAIN_CHECKBOX.MAIN_CHECK_BOX', ENABLED,PROPERTY_FALSE)
SET_ITEM_PROPERTY('MAIN_CHECKBOX.MAIN_CHECK_BOX', INSERT_ALLOWED,PROPERTY_FALSE)

nothing work !!

I'm an IS student who is having his training in some company , so I'm not an expert or something

so, please guys if anyone have any idea that will help me i will be grateful

Looks like it should work, do you get an error message?

the hole records?

Use get_item_property to check the enabled property has been set correctly.

A shorter version of your code might look like this:

begin
  go_block('ATTENDANCE');
  FIRST_RECORD;

  loop                     
    :ATTENDANCE.SIGGNED := :MAIN_CHECKBOX.MAIN_CHECK_BOX;
    EXIT WHEN :SYSTEM.LAST_RECORD = 'TRUE';
    NEXT_RECORD;
  end loop;

  FIRST_RECORD;
end;

I didn't quite understand what you meant by saying that "nothing works" ... what is "nothing"? Is it that code you posted doesn't check (or uncheck) all checkboxes, or is it that SET_ITEM_PROPERTY doesn't have any affect, or - bad news - nothing works at all?

Anyway, you might want to run the form in debug mode and see what is going on.

Well set_item_property always works, unless you get an error. Are you getting an error?
Have you checked there's no other code that enables the checkbox?

Then triple check.
There are exactly three options here:
1) You get an error when you try to disable the check box.
2) You aren't actually running code to disable the check box (code is being bypassed or references the wrong item)
3) Some other code is re-enabling it.

There are no other options.

So you need to debug your code to work out what's going on.
Run the form in debug mode or use get_item_property to check the property at various poinrs.
