In order to evolve Happiny into Chansey, you must make her hold an Oval Stone and then simply level her up during the day, no matter what level she is at (except at level 100).
You can find Oval Stones in Dustclouds inside Relic Passage, Rebirth Mountain and Clay Tunnel. Alternatively, you can buy it at the shop in White Forest (Monday to Friday) after defeating the White Treehollow (since your game is Black 2, you would need to exchange Keys with someone with White 2). The last resort is to trade with someone for a Pokémon holding this item.
Happiny is the only Pokemon that can evolve from a Oval Stone in Pokemon Diamond, Pearl, and Platinum. You will need to max its Happiness during the morning or day, let it hold an Oval Stone, and then level it up once. It will, then, evolve into a Chansey.
In Pokémon Diamond, you use the Oval Stone in order to evolve a Pokémon called Happiny however you need to give the Oval Stone to Happiny itself instead of using it on Happiny. Once an Oval Stone is attached to Happiny then you just need to level it up once while it's the day time in Pokémon Diamond and it will evolve into Chansey.
It evolves to chansey by holding a oval stone and making it happy. First, it hatches from it's egg and obviously is a Happiny and when it's leveled up holding an Oval Stone, it evolves into Chansey. Chansey evolves into Blissey via happiness. So the evolution is Happiny, Chansey, and Blissey.
If held, it evoles Happiny into Chansey when leveled in the day.
