Problem With Datalist C# ASP.NET

Question

Hello i have 2 pages. First page is Pets.aspx and second is Customer.aspx

 

In Pets page i have put datalist with pet pic and details..so it displays a list of pets with details.

How can i add a button to each data below the pet details and how can i redirect that button to the Customer page and autofill a few textbox in Customer page?
