The AsyncControl type exposes the following members.

Constructors

	Name	Description
Public method	AsyncControl

Properties

	Name	Description
Public property	AttachToRunningThread	If set, control tries to find already running thread to attach to on load
Public property	CancelAction	Action performed if Cancel button is pressed. If not specified then Cancel stops the worker.
Public property	CancelButton	Cancel button
Public property	ComponentName	Component name (Inherited from AbstractUserControl.)
Public property	ContinueOnAnyServer	If true, the async process and it's subsequent callbacks can finish on other server that executed the action. Disable with caution as there is no guarantee that non-sticky web farm will be switching between servers, and if it doesn't, the process continuation may hang. If possible, leverage ProcessData with serializable content (Data property) so that the process can continue on other server rather than using static variables to pass the data to the next request.
Public property	ControlContext	Control context. (Inherited from CMSUserControl.)
Public property	CurrentDocument	Current document (Inherited from AbstractUserControl.)
Public property	CurrentLog	Current log context.
Public property	CurrentPageInfo	Current page info (Inherited from AbstractUserControl.)
Public property	CurrentResolver	Control's resolver (Inherited from CMSUserControl.)
Public property	CurrentSite	Current site (Inherited from AbstractUserControl.)
Public property	CurrentUser	Current user (Inherited from AbstractUserControl.)
Public property	DisplayMode	Gets or sets display mode of the control. (Inherited from CMSUserControl.)
Public property	DocumentManager	Document manager control (Inherited from AbstractUserControl.)
Public property	EditedObject	Control's edited object (Inherited from CMSUserControl.)

Public property	Log	Gets the current log.
Public property	LogContext	Gets the current log.
Public property	LogContextNames	List of log context names separated by semicolon that should be received by this async control log from a general API call. Use empty string for context which logs messages that do not provide context. Direct logging to context always logs the message without checking the context.
Public property	LogPanel	Message panel where log is being displayed.
Public property	MaxLogLines	Maximum log length. (0 = unlimited)
Public property	MessagesPlaceHolder	Placeholder for messages (Inherited from AbstractUserControl.)
Public property	Parameter	Process parameter.

Public property	ProvideLogContext	If true, the async process provides a log context
Public property Code example	ResourcePrefix	Prefix for the resource strings which are used for the localization by the control and its child controls. (Inherited from AbstractUserControl.)
