Crescendo, diminuendo, hairpins, accelerando, ritardando, rallentando, etc.

I have been creating a score for the wind ensemble setting lately and when I view the parts (for instance Flute 1 or Trombone 3) none of the hairpins, ritardando markings, accelerando markings, and their ilk will show up in the parts. They all show up in the score, but the part has none of this. How can I make them attach to the part?
