The UpdateProgress control provides status information about
partial-page updates in Update Panel controls. You can customize the default
content and the layout of the Update Progress control. To prevent flashing when
a partial-page update is very fast, you can specify a delay before the Update
Progress control is displayed.
You associate an UpdateProgress control with an UpdatePanel
control by setting the AssociatedUpdatePanelId property of the UpdateProgress
control. When a post back event originates from an UpdatePanel control, any
associated UpdateProgress controls are displayed. If you do not associate the UpdateProgress
control with a specific UpdatePanel control, the Update Progress control
displays progress for any asynchronous post back.
