Hi Olivier,
When using an Inheritance Hierarchy for your database the best approach is to use Business Objects (POCO's) with an
ObjectDataSource component. A sample is available in the
How-To Bind to Business Object documentation.
Additionally, the
[DataObject] declaration in the sample will enable the ability to write specific methods and queries that can shape the data output in the ways you describe.
For example, the below methods from the sample get a list of products in different ways.
