HI all,

I have a form in which there is a check box(select all) which if selected selects all the records.
I am trying to implement the feature where if I unselect any of the record, select all check box would get un checked. here is my code so far

declare
	L_ind char(1):='Y';
	L_rec_count NUMBER:=0;
begin
	go_block('b_search_result');
	last_record;
	L_rec_count:=:system.last_record;
	first_record;
	if :b_action.cb_select_all='Y' then
		for c in 1..L_rec_count
	    loop
	    	go_record(c);
		    if :b_search_result.cb_select_single='N' then
			  L_ind:='N';
		   end if;
	   end loop;
	end if;
		if 	L_ind='N' then
			 :b_action.cb_select_all:='N';
		end if;
		
		exception
			when others then
			  message(sqlerrm);
			  raise form_trigger_failure;
end;

which is throwing the error NO DATA FOUND. I dont know how this error is being generated. Please help. Also let me know how can I check the value of an intermediate variable in a form?

I didn't look at your code too close as it would be hard to follow without the form and I am not downloading the form.
you do not mention anything about if any of the fields are database or non-database fields, whether the "all" field is in the same block or another, etc.
For me, if any of the checkboxes are unchecked, all you do is somthing like:

:block.the_all_field := NULL;

QED

Besides, your code is wrong - it'll never work. :SYSTEM.LAST_RECORD is either TRUE or FALSE, it doesn't contain record number.

Moreover, it can NOT raise NO-DATA-FOUND; it is raised by some other code. Which one? Run form in debug mode and you'll know.

You could try with WHEN-VALIDATE-ITEM trigger on the record's checkbox item, which would look like

if :b_search_result.cb_select_single = 'N' then
   :b_action.cb_select_all := 'N';
end if;

As LF points out your code is wrong, so as it stands it'll raise an ORA-6502 error, unless the go_block or last_record fires a trigger that causes another error.

Yes! your code seems wrong any how I tried to run your uploaded .fmb file but i am unable to open which form version r you using. What logic are your trying to implement while DESELECTING single checkbox and MY 2nd question is that in your form "SELECT_ALL" & "DESELECT_ALL" are properly working or not.

Yeah sorry it's wrong. It should have been :system.cursor_record;

Thanks for looking into. I have successfully fixed it now. Please see the below code -

declare
	L_ind char(1):='Y';
	L_rec_count NUMBER:=0;
begin
	go_block('b_search_result');
	last_record;
	L_rec_count:=:system.cursor_record;
	first_record;
	if :b_action.cb_select_all='Y' then
		for c in 1..L_rec_count
	    loop
	    	go_record(c);
		    if :b_search_result.cb_select_single='N' then
			  L_ind:='N';
		   end if;
	    end loop;
	else
	   	for c in 1..L_rec_count
	    loop
	    	go_record(c);
		    if :b_search_result.cb_select_single='N' then
			  L_ind:='N';
		   end if;
	    end loop;
	       	
	end if;
		if 	L_ind='N' then
			 :b_action.cb_select_all:='N';
		else
			 :b_action.cb_select_all:='Y';
		end if;
		
		exception
			when others then
			  message(sqlerrm);
			  raise form_trigger_failure;
end;

The first IF statement is pointless since you do the same code in both sections of IF.
The simplest way to loop over records is:

first_record;
LOOP
  <do_stuff>
  EXIT WHEN :system.last_record = 'TRUE';
  next_record;
END LOOP;

You don't have anything to put the cursor back in the record it was in at the start, it'll always end up in the last record regardless of which record the user had last selected.

And as LF pointed out above you don't need to do any looping at all. You could just set the select all checkbox when one of the detail checkboxes is changed.

Sure brother

Begin
go_block('CHKBOX');
    first_record;
 LOOP
    EXIT WHEN :SYSTEM.RECORD_STATUS='NEW';
 if :CHKBOX.CHK = 'Y' then 
     DELETE_RECORD;
   else
    EXIT WHEN :SYSTEM.LAST_RECORD='TRUE';
NEXT_RECORD;
   end if;
END LOOP;
--COMMIT;
end;

Regard
Mughal
