You have to add it to whatever backing store you are fetching the rest of the data from: your Database, config file, CSV, XML, JSON, or Excel file for example.

We have no idea where the rest of the data in your DGV comes from, so we can't give you specific help.

:sigh:
No, the *rest* of the data in your DGV, not the one new row.
