Put "Select all" checkbox into a control block. When you check that "select all" checkbox, loop through all records in a tabular (data?) block and set all checkboxes to "checked".

Hi,
As you said I have written like this but only one check box is selected.

BEGIN
  WHILE :SYSTEM.LAST_RECORD='TRUE' LOOP
  IF :CONTROL.SELECT_ALL = 'Y' THEN
  		
		GO_BLOCK('XX_TEST_DBBLOCK');
	 
		FIRST_RECORD;             
		:XX_TEST_DBBLOCK.REQUISITION_CHECKBOX := 'Y';
		
	ELSIF :CONTROL.SELECT_ALL = 'N' THEN
		GO_BLOCK('XX_TEST_DBBLOCK');	
		FIRST_RECORD;
		:XX_TEST_DBBLOCK.REQUISITION_CHECKBOX := '';
		
		END IF;
		NEXT_RECORD;
	END LOOP;
END;

Read what you wrote, in plain English.

loop while a condition is met
  If SELECT ALL is checked
     go to tabular block
     position to its first record
     check the first record's checkbox
  else
     go to tabular block
     position to its first record
     unckeck the first record's checkbox
  end if
  go to next record
end loop

You are now in the second record. This is what you do next:

  If SELECT ALL is checked
     go to tabular block
     position to its first record
     check the first record's checkbox
  else
     go to tabular block
     position to its first record
     unckeck the first record's checkbox
  end if
  go to next record

You are again in the second record. And the circle goes on and on.

Perhaps you should first write pseudo-code; once you are satisfied with it, write "real" code.

Also, please, read (again) this message.

Also, why this:

WHILE :SYSTEM.LAST_RECORD='TRUE' LOOP

Under what circumstances is that true?

OK then, here's how you might try to do that; adjust object names that don't match your own.

if checkbox_checked('buttons.cb_select_all')
then
   -- SET ALL CHECKBOXES
   go_block('tabular_block');
   first_record;
   
   loop
     :tabular_block.cb_checkbox := 1;
   	  
     if :system.last_record = 'FALSE' then
        next_record;
     else
        exit;
     end if;
   end loop;
   
elsif <fill in the code which would remove all checks>
