jquery ajax and asp.net data entry form

I have a pretty big data entry form which has many text fields which are dynamically added on the browser by the user. So i can not use server side controls such as asp:TextBox.

What would be the best way to submit the form and capture all the data on the serv开发者_如何学JAVAer side?

I use asp.net 3.5 (web forms)

1. register a hidden field in your asp net page
2. put your changes on client side into it.
3. load hidden field in postback
4. VALIDATE SOOO MUCH!
