Sequence property
As used with containers
Use the Sequence property to specify the order of components within a container. Windows client manages this sequence automatically for most containers.
For FormPage components, you must specify a zero-based sequence number for each form page.
As used with event handlers
The Sequence property indicates the position of an event handler in the execution order of handlers for an event. Zero (0) indicates that there is only one event handler.
If any event handler returns an error, subsequent event handlers are not executed.
