Add record to a database without postback

Hi,

I need a good idea how to do something like this:
I've to add new entries to a database using a web interface.
The "Add" button is outside the input fields in a footer of the page so I can't do anything in one updatepanel (customer like to have so).
So it would look like this:

Header
-----------------------------------
M | Input1
E | Input2
N | Input3
U | Input4
-----------------------------------
Add

I like to only let the main part of the side refresh after a "Add" and start again with empt fields.
My only idea how to do is to parse the input fields with javascript, submit the data and send a refresh to a updatepanel container of the input fields.

Is there any easier way how to do?

Thanks,

Andre
