title: How to limit the number of post values on UpdatePanel?
body: <p>I have notice that the <strong>UpdatePanel post every field included on the form</strong> on every trigger.</p>
  
  <p>But in most of my cases I use 2-3 UpdatePanels at the same page, and each one is independent.</p>
  
  <p>When I click for update the one panel, then my page receive all the input data of the page (ok this is logical) but I won to read only this UpdatePanels data and act according, and not the other panels data.</p>
  
  <p>So I see that a lot of traffic is happened this way.</p>
  
  <p>So is there a way <strong>to say to one UpdatePanel - send only my input data</strong>, and not everything found on the page. ?</p>
  
  <p>Thank you in advanced.</p>
