You have five aces there. Which of you had the Ace of Trump?
First of all, you had no way to know if the dealer had a perfect loner there. As you say, you didn't order up the right... I might be a bit miffed at you if you ordered the right into my hand without having three trump but I wouldn't throw the game over it. Yesterday, I had a partner order me up (I was dealer). I had left, ace, king, queen, and a green ten. Up card was the right. Yeah, I was a bit miffed about that and I would have won the game had he let me go alone, but I didn't start acting like a jackass following it.
As Wes points out, you should have gone alone yourself with that hand. Realistically, with you ordering the king to your partner (and thus eliminating it from play), the only way you're going to get euchred is if one of your opponents is holding a Dutchman and in that case, you're going to get set whether you bring your partner along or not.
This is a good example of why you always want to get a good idea of your partner's bidding style. If I'm in the second seat, the only time I'm ordering up the right is if I'm holding at least three trump. The exception to this rule though is if I've seen my partner bid very timidly. Something like him passing on the right and then playing another card from the same suit and a side ace or two later in the hand. With a partner that I know will pick up if he's got anything at all in his hand, I'll usually only call with a hand that I'd be better off going alone on myself.
For example, in second seat holding this:
Upcard is the

.
I'll absolutely order my partner up, but then I'll go alone myself. With the right out of play, I'd have to have an opponent in third seat with a killer hand (three trumps himself) to stop me. If you're playing using that app in which a lone player always has last play on the first trick, it's nearly impossible to stop this.
