I have a web form that has multiple ListBoxes, TextBoxes, DropDowns. If I put one UpdatePanel around the whole page, I noticed the page is slower. Is this because, every control is being updated? If I put different UpdatePanels around each control, I noticed the page has a better response. Is it right to assume that this is because I have more control of which parts of the page are updated based on selections from ListBoxes and DropDowns for example?
Thanks,

each update panel generates a round-trip to the server (i assume you’re using a timer or something to cause this)
the general rule would be to group controls in an update panel that must change together, otherwise separate update panels makes more sense
