3 UpdateProgress Control

The UpdateProgress control enables us to provide feedback about the progress of the partial page rendering. Please note that for initial page rendering, UpdateProgress control content is not displayed. UpdateProgress control is not an independent control it must be associated with an UpdatePanel control.

A page con contain multiple UpdateProgress controls provided it has been associated with different UpdatePanel control. To associate UpdateProgress control we need to set AssociatedUpdatePanelID property to any of the UpdatePanel id. If any postback event occurs from inside an UpdatePanel control, its associated UpdateProgress control content if any are displayed.
