Sys.UI.Control raiseBubbleEvent Method
Calls the onBubbleEvent method of the parent control.
When the raiseBubbleEvent method is called, the source object and args values are sent to the onBubbleEvent handler of the current control. If onBubbleEvent returns false, they are sent to the onBubbleEvent handler of the parent control. This process continues until an onBubbleEvent event handler returns true, which indicates that the event has been handled. Any event that bubbles to the Sys.Application instance without being handled is ignored.
