Narrative:

After the first officer made an uneventful landing; at taxi speed just before I was going to take over the controls in the right turn on to taxiway B; the aircraft did not seem to have directional control and no braking; with the right pedal fully depressed on both sides. As the left gear and the nose wheel departed the paved taxiway I retarded both mixtures so the prop would not hit the taxi edge lights; the left engine stopped and the right one kept running (both fuel pumps were on low). The aircraft came to a stop and I decided to restart the left engine and taxied to the terminal; the first officer (first officer) and myself were surprised as to what happened; and we both figured it could have been a gust of wind. Upon arrival at the terminal I turned towards the 3 passengers and made sure they were ok and told them that we probably hit a gust of wind; they seemed undisturbed. The first officer and myself inspected the landing gear and the propellers and noticed a small nick in one of the blades of the left propeller. I immediately called the chief pilots office; and gave the manager on duty a description as to what happened. I wrote up the aircraft for inspection.
