How do we get data from more than one table into a grid, if the tables are 1-to-1?

A simplified example.
A Company table has : key | name
An Address table has : key | address

And we want a grid with : name | address

As far as I know the grid cannot databind to more than one dataset like, column1 = companyDataset.name, Column2 = addressDataset.address.
The query could of course select both name and address, but then saving the data gets difficult.
Any help or recommendations appreciated.
