Hi,
probably already mentioned somewhere, but I couldn't find it, so:
Having the fairly standard Customer 1<->n CustomerContacts, I create self-servicing code.
Then create a form, drag onto it a CustomerCollection and a bindingSource1 bound to that collection.
Now create a DataGridView bound to:
DataSource=bindingSource1, DataMember=CustomerContact
This should automatically show all contacts for the current customer (and it does ;-)), but when I edit the DataGridView's columns and add a new column or change the DataPropertyName for a column I get the list for the CustomerEntity, not the CustomerContactEntity 'sublist'.
(LLBLGenV1 does show the contact-fields)
If I just create 'dummy'-columns and type the fieldnames manually, then the grid works as expected.
