ASP.Net WebForms problem

[Big E]

I'm using ASP.Net and 2 webforms.
The first web form is open and users click a hyperlink on the datagrid and
that pops up a 2nd form with more details. If the user likes the record he
will click a button that will send that info into textboxes on the first
page.
Problem: I can't use server side code because I will lose the info on the
first page. What I need to do is use some client side code that will simply
put data from the onclick like: PAGE2.Textbox into PAGE1.Textbox.
Would I use Javascript or VBScript or simple HTML. Does anybody have sample
code for this?

Thank you,
Big E

PAGE1 should open PAGE2 with a showModalDialog call. PAGE2 should put the
result info into window.returnValue. PAGE1 will get the info as the result
value of the showModalDialog call and will put it into the textbox.
