// Refreshing UpdatePanel Content
//
// When partial-page rendering is enabled, a control can perform a postback
// that updates the whole page or an asynchronous postback that updates the
// content of one or more UpdatePanel controls. Whether a control causes an
// asynchronous postback and updates an UpdatePanel control depends on the
// following:
//
// * If the UpdateMode property of the UpdatePanel control is set to Always,
// the UpdatePanel control's content is updated on every postback that
// originates from the page. This includes asynchronous postbacks from
// controls that are inside other UpdatePanel controls and postbacks from
// controls that are not inside UpdatePanel controls.
//
// * If the UpdateMode property is set to Conditional, the UpdatePanel
// control's content is updated in the following circumstances:
//
// o When you call the Update method of the UpdatePanel control
// explicitly.
// o When the UpdatePanel control is nested inside another UpdatePanel
// control, and the parent panel is updated.
// o When a postback is caused by a control that is defined as a
// trigger by using the Triggers property of the UpdatePanel
// control. In this scenario, the control explicitly triggers an
// update of the panel content. The control can be either inside or
// outside the UpdatePanel control that the trigger is associated
// with.
// o When the ChildrenAsTriggers property is set to true and a child
// control of the UpdatePanel control causes a postback. Child
// controls of nested UpdatePanel controls do not cause an update to
// the outer UpdatePanel control unless they are explicitly defined
// as triggers.
