As you scroll through the parent entries the primary key of the current parent is passed down to child entity where it will enable you to scroll through all available entries one at a time. The primary key of the current child entity is then passed down to the grandchild entity where it will enable you to scroll through all available entries one page at a time.

You need to ensure that the SELECT list in each SQL query includes the primary key for that table. If you miss this out there is no value which can be passed down to the chiold entity.

If the are any differences between the name of the primary key in the parent table and the name of the corresponding foreign key inb the child table, then you must convert the field name manually in your code as the framework cannot do this automatically.
