After you finish your Pokedex, talk to Professor Rowan and Professor Oak and they will give you the National dex and the Poke radar.
Unlike in other games you just have to see the Pokemon not catch them but when professor oak gives you the natinal pokedex you have to catch the Pokemon
by finishing the first pokedex and then professor oak give you the national pokedex

The event scene in Pokemon Pearl where the player meets Professor Oak on route 224 is part of a Nintendo-sponsored special event in order to obtain the legendary Pokemon, Shaymin. The player must be involved in the special event to obtain the key item called Oak's Letter, and afterwards Professor Oak will appear on route 224.
