opens a form into another form

hey!.
My question is i have a Web Form with some textboxex and one button(server s
ide).
As soon as i click on this button,it performs some server side calculations.
As soon as it finishes,i want to open an another web form into this first(al
ready opened form)without closing first form.
How can this possible?

I appreciate that English isn't your first language, but can you explain in
a bit more detail what you mean by opening a form *into* an already open
form...? Are you talking about an iframe...?
