persist data in the form

There is a ASP.NET web form for user input data, user can also click one
button to trigger another asp.net web form for lookup purpose. My problem is
when the user choose data from the lookup form and back to input data, the
data in the input data form was refreshed and become blank. How can I
persist those data in the input data form'
