>I read this quickly, It seem's for row editing only ?

Just so I understand, is you question "Can you only edit one parent at a time?" If that is your answer, yes, that is true. However, you can freely edit as many rows of any number of children you want.

If you need to edit another parent at the same time, you can instance another form, which will create another instance of the data controller. Both data controllers by the way, share the same connection.

Does this clarify things?

Are you talking about a UI element - (listbox) here? If so, you need to understand that everything in the docs you are reading is concerned with the data and business tiers - which may or may not be combined based on your architecture. Elements of the UI have no place in that discussion.

You can however, create your own UI classes that incorporate elements of DataClass 2000 to achieve what I think it is, you are looking for. For instance, we have grid subclasses that hook into child cursors. We have controls that enabled/disable themselves based on the cEditMode Property.
