I'm trying to add panels dynamically with out clear the previous. I mean initially I have just 1 panel with some textboxes, in the bottom of the page I have a Button to "Add a new panel", ok i just want to click that button and render in my page a new panel without deleting de previous one, and if i have added 3 panels when i click the fourth time the button get the 4 panels rendered in the page. This can be done?? Thanks for your support!!!! Hi, I’ve been reading your posts and are great but I have a question to help me in my development.

It seem i just leave it re-generate every times on Page_Load and keep the same ControlID is the easy way to solve my problem. Great Hints,

Looks like that one got ya stumped, eh? ;-) Just as an FYI, as a writer, you really ought to refactor this series of articles. Most programmers are interested in the right way to do something, and why it's right. You have whole articles (Part 1 and Part 2?) that essentially tell people the wrong way to do things...so why would you want someone to read that? I thought Part 4 was supposed to be about AJAX?
