No, you must trade the certain Pokemon that need to be traded to evolve to make them evolve.
Kadabra does not evolve via leveling up, it must be traded to evolve it into an Alakazam.
a Pokemon that has to be traded to evolve can be any lvl you want it to be you get it the Pokemon the same lvl that your Pokemon was it does not grow a lvl when it is traded
Some Pokemon can only evolve with Evolution Stones. Others can only evolve when traded. Most, though, must reach a certain level to evolve. The rest don't evolve at all.
If you mean evolve, get a Pokemon, eg Buizle, and get it to a high level. In Buizle's case you need to get him to level 30. But some Pokemon need to be traded to evolve. Like Kadabra, Machoke and Gravaler. But others need to hold and item and be traded like Rydon must hold the Protector and be traded to evolve and Dusklops must hold the Reaper Cloth and be traded to evolve. Then Clampearl must hold the deep sea scale or the deep sea claw to evolve. Then there are some, like Palkia, Dialga and Giratina that can not evolve. Ledgondaries are unable to evolve and you will get the odd Pokemon that can't evolve like Parchirishu and Farfeched. And Pokemon that are at their last evolvment will not evolve again, like Pidgeot, Floatzel, Roserade, Stunktank and many more.
Gravelers are a part of a group which cannot be evolved by conventional means, it must be traded and upon receiving the Pokemon it will evolve into Golem
No, Pokémon cannot evolve while they are being migrated or transported to another game, Pokémon that need to be traded to evolve must be traded to evolve.

Bodore evolves into Gigalith when you trade it.
Trade it for a Shelmet. Both the Karrablast and Shelmet will evolve upon completion of the trade. This is the only scenario where specific Pokemon MUST be traded for either of them to evolve.
