Peter van Mierlo EVENTSOFT | Hi
I have added an example for clarification.4 tables: - contact - group - groupcontact (contains contacts per group) - messagesend then - groupcontact has a master / detail with group - groupcontact has lookup fields to contact to have contact information issue formMainWhen navigate the dbgrib above the corresponding group members are showed in the dbgrid at the right.When a ADD a new record, the group members in this dbgrid are still visibile but because there is no group selected the dbgrid must be empty.I think i have a wrong master / detail and the lookup but don't see it anymore where i going wrong |

<<I think i have a wrong master / detail and the lookup>> You certainly have The DBGrid is linked back to MessageSend, your master/Detail is linked back to GroupList so that when you click the button to create a new MessageSend record GroupList is not affected at all. GroupContactList should have: IndexFieldNames: GroupID MasterSource: dsMessageSend then it should work Roy |
