The afterrender event may be called from web pages developed in Web Designer and processed by a USoft page engine service.
This event applies to single-record UI controls only. For multi-record UI controls, use the renderrow event instead.
How to use
Find or create an Event Listener object with Event Type = afterrender. Event Listeners are in the Web Designer Controls catalog:
Insert the event listener into the Page object. Insert a callClientScript action into the event listener. Use this action's Script property to code the behaviour that you want to see when the event occurs.
