Table 5-6. Properties of the UpdateProgress Control
Property Name Function
AssociatedUpdatePanelID ID of the UpdatePanel control that the UpdateProgress control displays
the status for.
DisplayAfter The value in milliseconds before the UpdateProgress control is
displayed.
DynamicLayout A value that determines whether the progress template is rendered
dynamically. If set to false, it will take up the required space at all times
even if the progress content is not displayed.

In such cases, it??™s helpful to use the UpdateProgress control to notify the user about
the running status of the application.
