ASP.NET and popup pages...

I'm not an ASP.NET expert by any means, so I post this question to the Blogsphere...

I have a student who is a Lotus Notes developer, who commonly uses javascript to open a “popup window” from the browser as a dialog box, have the user select some values, and post those results (somehow) back to the calling page. This is easily enough done in Windows Forms, but is there a corresponding paradigm in ASP.NET?

We've been talking about postbacks and linking to different pages, but never any parent/child or dialog type page to page relationships. I think the paradigm for ASP.NET applications is just different.

Is that right? Or can it be done (easily)?
