Found the problem. The property names that are automatically created when creating the DataSource ("Affect properties" checkbox is checked) are prefixed with database, schema and tablename. Renaming the properties to match my field names fixed my problem.
The irony is that I has just completed the online training and specifically remembered the instruction to make sure "affect properties" is checked so you don't have to go through pain of creating fields. It is still painful to have to rename them all.
That did not work for me. I do not use query builder, I just type in SQL in the window. But I went into query builder and tried checking that box, and also unchecking it. Neither one fixed the problem. No matter what I have for my property name, I still do not see the values in the data grid. My SQL statement is "select foh.customer_number as cust_num..." so I tried setting the property to foh.customer_number and cust_num, and something totally different. None of those worked.
Anyway, thanks for posting that, glad it worked for you.
