A DHC8-400 flight crew failed to note that maintenance had left the alternate gear door handle open during a required line check. As a result they were unable to retract the gear after takeoff.

Narrative:
We were notified of required maintenance line check inspection on the aircraft prior to our return flight. After maintenance signed the aircraft off; I proceeded to conduct a walk-around. We were trying to get an already significantly delayed flight out as quickly as possible. We briefed the flight per SOP's and conducted a before start and engine start checklist before pushing back. After takeoff and 'gear up' command; I raised the gear handle and the landing gear would not retract. 3 green lights; as well as the 3 red unsafe lights and gear handle light remained illuminated. After safely navigating out of the terminal area; we ran the appropriate QRH checklists. I scanned the flight deck and discovered the alternate gear door hatch opened. We contacted company and maintenance by radio; and followed recommendations to close the hatch and raise the gear. This was successful. After another gear cycle to ensure proper operation; we continued to our destination without incident. We need to develop a standard aircraft configuration when control is transferred from flight crew to maintenance and vice versa. If switches and levers are always in the same position; we can minimize risk of overlooking these in the preflight.
