Narrative:
On takeoff leg; pilot flying; first officer (first officer) reported no electric trim. I tried my side to no avail. We continued the flight for the time being using manual trim. Since we were on a departure we delayed referring to the QRH so both pilots could concentrate on flying/monitoring aircraft performance. During climb we engaged the autopilot anticipating a 'stab out of trim' caution light if the autopilot trim was in fact inoperable also. The light illuminated so we disengaged the autopilot and continued with manual trim. After level off we referred to the QRH and complied. After discussing our situation we determined that in this day and age it would be wise and prudent to recover the trim system if possible. I cycled the trim circuit breaker and trim returned to normal.
