You've not given any specifics so it's hard to answer. If this is a new problem, my answer would be different than if he's never been good at this and now it's coming to a head.
If you've "tried everything" maybe you are trying too many things and there's no routine? I see a lot of books recommended by other moms for issues like this - "1 2 3 Magic" is a popular one. You can get something from the public library too - maybe try two to find something you both agree with and can sustain. That is the key!
Kids have a built in respect for their teacher and principal. When my son didn't want to get his act together to go to school, I told him, "Fine, I'll take you in when you're ready. Remember though, if you don't go on time, you have to stop in the office and check in. And while you're there, you can sit down with the principal and explain to her why you don't think it's important enough for you to get dressed, eat breakfast, and get to school on time. I'm sure she'll be very interested in your reasons." He never gave me a hard time again.
Your son is somehow getting rewarded for his behavior - he's getting attention, even if it's negative attention. You need a calming routine that is the same every night. Whatever those elements are, they are the same every night: bath, brush teeth, get in bed for a story or a song or quiet talk, whatever calms him. I'd take away anything really stimulating for an hour before - TV off, games and toys put away, running around curtailed, and so on. Make it book/story time maybe, and create a get-ready-for-bed routine.
If he keeps getting up, put him back in his room without talking to him. No glasses of water, not conversation, no lectures, no threats. If he's overtired the next day, then take away all the things that kept him revved up. Some parents play down the fact that the evening is their time together. If he thinks his missing out on something like TV, he'll be more inclined to get up. If he thinks the hours after his bedtime are spent doing laundry and washing dishes, and that anyone who stays up has to do those things, he may be less inclined to find that time appealing. But you have to be able to sustain that and not have him get up and find you watching TV, you know?
So that's why I say both parents have to agree on a style of discipline and be firm about it, with no rewards in any way (including a lot of attention or cajoling) for a child who keeps getting up. Kids don't understand that being overtired is a problem - they only think about NOW.
