本文介绍了一种在WinForms应用程序中实现父子表数据绑定的方法。通过使用BindingSource组件，可以轻松地将父表（客户信息）与子表（订单信息）关联起来，并在两个DataGridView控件中显示这些数据。此外，还展示了如何设置导航栏以方便用户在记录间进行切换。

private void OnFormLoad(object sender, EventArgs e)
{
// Get the data set with parent / child tables into a data set
CustomersDataSet customers = CustomersDataSet.GetCustomers();
// Set up the data sources normally for the first grid
m_CustomersBindingSource.DataSource = customers;
m_CustomersBindingSource.DataMember = "Customers";
m_CustomersGrid.DataSource = m_CustomersBindingSource;
// Set up the data sources for the child source to point to
// the parent source, and the contained relation
m_ChildOrdersBindingSource.DataSource = m_CustomersBindingSource;
m_ChildOrdersBindingSource.DataMember = "FK_Orders_Customers";
// Child grid to child connector
m_OrdersGrid.DataSource = m_ChildOrdersBindingSource;
// Navigator to parent connector
m_BindingNavigator.BindingSource = m_CustomersBindingSource;
}
