Can you describe the grubs and where you found them on the plant?
Digging up the bulbs just as they are coming into flower may not have been the best course of action (too late now) as the bulbs need their leaves to help build up a food store in the bulb in order to produce a flower next year. Let's see if we can identify the pest as a matter of interest...otherwise you'd probably have more success with fresh bulbs next year.
If the grubs were in the roots it could well be vine weevil....it is also possible that 2 different bugs attacked your gladioli - 1 on the leaves another 1 on the roots!
