By definition, the child view typically uses the parent's unique id in a view parameter.

Check out the sample Project Manager application's ProjectsForm. Both the Contacts tab and Tasks tab contain business objects that are children of the parent business object on Page 1.

In the child business object's PostInitHook() method you will see code that is used to set their associated view parameters. Also check out the section "Specifying and Creating View Parameters" in the Mere Mortals Developer's Guide.
