I've got 3 tables. Table1 is the master table and tables 2 & 3 are detail tables related to table1. On the VB.net Windows form I've added several textboxes binded to table1 as a header and a tabcontrol containing seperated pages for each detail table. Each containing a datagrid and navigator. I've managed to setup a relation between table1 and table2 and all the controls works fine but for the life of me I can't get the relation between table1...
