Some elements, like tables and forms, contain an Events node in the designer window that, when expanded, lists all the events that are associated with that element. If you need to add supplementary behavior that doesn’t currently exist in an element, you should create an extension of that element, and then add an event handler to the extended element.
The following are methods for event handlers that are pulled from the CustTable table. These methods can be copied and added to your extended element or class by right-clicking the event in the element designer window and selecting Copy event handler method.
