Transfer data from one page to another.

Hi, I'm just a beginner. 
I want to create a web page in ASP.NET where user fills his name, address, city and after that  clicks on  "next" button. Then, he moves on another page where he has to submit his contact details.. 
So, after filling  the contact details, he again clicks " next"  button and  sees all his detail (name, address, city, contact no)  
so please help me out.. How to transfer data from one page to another...
