I have a User Record and ManagerId field in It.Given a particular User ID i want to get all users under the given user ID at all levels.
Is this possible in apex.This is not related to Role hierarchy.

I am sending a server side request to Gdrive to fetch the Authorization code.Gdrive does send me the code and redirects me to the mentioned redirect URl.
But in the above case my Page is refreshed and all the controller variables are reset.Can anyone suggest a solution.
Ihave created a picker to download files from Gdrive using Google javascript API.Can weget the authorization code via javasript?
