how to postback part of a page in ASP.NET
I know that update panels help rendering part of a page, but what I'm asking is how to postback part of a page to server not all. I have a page that has several inside each a form that postsback some info to server. I want each submit button to postback only it's own form information not all others too.  
The actual problem is that when I submit one of the forms required field of other forms won't let me do the postback. So a rephrased question might be, how do I disable validation for a button and enable it for others?
