Start with the DataGridView.RowPrePaint[^] event: it is called for row just before it is drawn. In it, check the expiry and set the foreground / background colours appropriately.

You will also need a Timer to Invalidate the DGV so that it does get repainted.

To set a "countdown timer" for each row, use the same event and timer, and update the row "countdown" column.

Thank you, unfortunately I can not find it in Properties for DataGridView

It's an Event, not a property.
Properties are for data, Events are for action as a result of things happening ... Look at the properties pane and click the little lightning bolt.

I did, but there is no event RowPrePaint

Take a deeper look. If this event is available in MSDN documentation, then it should be available in your project, unless it isn't a WinForm project.

What events can you see?

Data Grid View is in Windows Form

Yes, and it has a RowPrePaint event: what events can you see?

Beginning with Row, I can see only RowDetailsVisibilityChanged, nothing else

That's not a DataGridView, it's a DataGrid - which means it's WPF not WinForms.

You need to be accurate about these things when you ask questions!
