Hi Jerry_lth,

We have provide a good sample on MSDN. Please check this page:

• How to: Create a Master/Detail Form Using Two Windows Forms DataGridView Controls

In the above sample, it creates a master/detail form using two DataGridView controls bound to two BindingSource components.

Hope this helps.
Best regards.
