how to add multiple row from DataGridView to a table in the DataBase?

in my DataGr开发者_如何学PythonidView there are about 2 or 3 rows about the Supplier data it is about Supplier data ,,as there might be one product i get from 2 or 3 suppliers how to add the Suppliers_ID (FK) to the Product table in the data base from the data grid view when i click on a button (Confirm adding) and to avoid the data redundancy i think it might be saving the 2 or 3 Suppliers_ID as Records but i donknow how to do this ?

You need to create a master-detail relationship between your two tables. This below link is for DataGrid but you can use the same logic for DataGridView:
