I have notice that the UpdatePanel post every field included on the form on every trigger.

But in most of my cases I use 2-3 UpdatePanels at the same page, and each one is independent.

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.

So I see that a lot of traffic is happened this way.

So is there a way to say to one UpdatePanel - send only my input data, and not everything found on the page. ?

Thank you in advanced.
