Pessoal se alguém puder dar uma olhada o que está errado em meu fonte, o cadastro máster/detalhe só está gravando o registro pai, os filhos (detalhes) não estão gravando e o sistema não retorna nenhum erro e anda dá mensagem que o registro foi gravado com sucesso.
Porém não está gravando no BD os detalhes vou colocar o fonte das classes modelos e o form de controle.
