    I'm new with creating multi-level relationships with the DataControl. I've gotten a simple master-detail pair working, but I'm trying to add a third level below the detail.

    On ComponentOne True DataControl (8.0):

    What test is being performed by the DataControl that causes the design-time message "Linked control B can't be the Master of C" where A, B & C are True DataControls each connecting to a SQL Server Table (adCmdTable)?

    I'm trying to create a three-layer relationship, where table B has a foreign key pointing to the primary key of table A, Table C has a foreign key pointing to the Primary key of Table B.

    Control A has its Master property blank, Control B has its Master property set to Control A, and Control C has its Master property set to Control B.

    Any help would be appreciated.
