Fields for expanded values

when I am accessing with a $expand clause 

how do I get the expanded fields in the field list of a TXDataWebDataSet
that is connected to that table.
I have added the expand clause to the querystring property.

You can create fields which names contain dots, like "Country.Name", "Country.Id", etc.

Or you can set SubPropsDepth property:

Expanding upon ShahRahul's question;

If you have a table which references another table that also references other tables, how do you get the second tables expands into TField?  sort of a expand and another expand.

Keep adding dots.
