Yes, Darwin,
If one of the tables are different and there's no relation between the two
datasets on different tabs, you need to use a new DataAdapter and generate
another dataset.
Since you don't need to update the data source, the solution to the
many-to-many issue might be right. However, If you need to update the data
table, you can set up a many-to-many relation between two tables and bind
the data relation to the datagrid. You can refer to the link I gave you in
my former posts. You just need to change the relation to many-to-many.

| I'm not sure if I did it the way I was supposed to. I
| could not just clone the dataset so in design mode I just
| generated a new dataset using the specific tables I
| needed. I needed one of the tables to be slightly
| different from one in the original dataset so I needed a
| new dataadapter as well. In no case do I need write
| access to any of the tables.
|
| To solve the many-to-many master-detail issue, I changed
| the detail select statement to do a join with the cross-
| reference table and then created a relationship between
| the master and detail tables. If I needed to update
| these tables this solution would not work.
