Query String - Querystring To A Hyperlink In .net ?

two aspx pages that i have.

First one is a table with results populated from the sql server backend. The first holds the "FirstName". I want this to have a hyperlink, so when i click on this, it should goto the second aspx page and show all the data in sql server for that "Firstname". the data is in 3 other tables based on firstname, which is phone, address and hobbies.So -

FirstName
Samuel --> clicked on it
redirect to second page -

Samuel -

Phone Address Hobbies
3104445656 123 main st Climbing

if i need a querystring or is there another solution (better solution). Also how do i capture the querystring in second page?
