Larry,

There's always several ways to do this sort of thing.

If your two DataTables are part of the same DataSet, you can set a relationship between them (I don't use relationships much, and I'm not 100% sure that the Tables have to be part of the same DataSet, but I think so). If you do this, then you'd DataBind your TextBox to the relationship.

Another option (which does not require the tables to be in the same DataSet) is to DataBind your TextBox to a DataView of the Product table, and as you navigate through the OrderDetail table, you change the RowFilter of the Product table's view.

That should get you started but don't be afraid to ask more questions. =)
