Set Line color in dG?

[Prothero-ELS]

Zryp,
What I wanted to do is make a distinction between data that was retrieved from a database and data that was entered but not yet stored. A datagrid is. Way overkill for what I’m doing, but .... the button that accesses the datagrid data to get the specific line is for testing only.
