Wear pants and a blouse or a pantsuit. That is dressy enough for a high school graduation. Your granddaughter (or your daughter or son) should make arrangements with the high school.....not you. There should be a section which is reserved for elderly or others who cannot climb the stairs.
Also I would not dress up to much. My son graduated last year and while you want to look nice don't over dress.Wear a nice white dressy blouse and a pair of dressy slacks or skirt with a pair of nice flats.Make sure your hair and make up is the most important thing. And congragulations to your grand daughter.
