You can't, the game won't let you transfer items from any other game apart from Pokemon Black or another copy of White.
you are unable to send any items from the past games to pokemon black/ white
after you beat the Pokemon league
The only way to get palkia in Pokemon white is to trade from other games
It is the same as any other games, but you can't trade with other pokemon games. You can only trade your pokemon from the different generation games, you can't give your white version pokemon to the earlier generations.
They are Dialga, Palkia and Giratina's hold items, though work for other Pokemon too. It is simply a way to get these hold items into the game, as should you choose to migrate them from other games, they are not able to bring held items with them.
You have to transfer from other games so no
Because you can't trade items from the GenIV games, they needed other ways to get certain items into GenV. Since you can migrate Dialga, Palkia and Giratina across, it's only fair that they can still somehow get their orbs in Black and White.
leave celeby n your PC box not on Pokemon black or white and it should probably say no:1 items (Pokemon) and it will save the games
No. Generation V Pokemon are only available in generation V games.
If you are looking for Zorua or Zoroark, they can only be obtained in Pokemon Black and White, and they can not be transferred to other Pokemon Games.
You cannot trade Pokemon on from other games (unless it's Pokemon black/white) until you have defeated the elite four.
You can only trade items by attaching an item to a Pokémon and then trading it between Pokémon Black and White games only. You cannot bring items from Pokémon Diamond, Pearl, Platinum, HeartGold or SoulSilver into Black or White.
