PushButton controls cannot be used to publish an IgnoreChange ControlEvent, SelectionDescription ControlEvent, SelectionSize ControlEvent, SelectionPath ControlEvent, SelectionPathOn ControlEvent, SelectionAction ControlEvent, SelectionNoItems ControlEvent, ActionText ControlEvent, ActionData ControlEvent, SetProgress ControlEvent, or TimeRemaining ControlEvent.

You can use the following attributes with this control. To change the value of an attribute using an event, subscribe the control to a ControlEvent in the EventMapping table and list the attribute's identifier in the Attribute column. Enter the identifier of the ControlEvent in the Event column.
