// 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.
