Гуру помогите плиз! Знаю как добавить данные в DataGridView из родительской формы, а как из дочерней что то не получается...

Когда DataGridView находится на родительской форме:

int patientID;
patientID=Rand.Next(); 
this->PatientTableAdapter->Insert(Rand.Next(), textBox6->Text, textBox5->Text, textBox4->Text, comboBox6->Text, true, Convert::ToDateTime("19.05.1987"), 12, 123);
this->PatientTableAdapter->Fill(this->bd_RegistraturaDataSet->Patient);

А как с дочерней???
Если пишу этот же код выдает ошибки:
