If the cell value fails validation, set the Cancel property of the System. This causes the Data Grid View control to prevent the cursor from leaving the cell.

The problem is being unable to cancel the moving from row to row (and, as such, attempting to save the changes).

Custom row validation is done using the Ending Edit and Validation Error events.

In the Ending Edit event, the custom validation is provided and in the Validation Error event, you can decided if you want to allow the row to exit edit mode in the case where the values of one or more of its cells do not pass the validation process (see Example 1).

As far as I can tell, the code on your site only helps with validating the data, not stopping the Row Leave event entirely.

This displays an error icon with a Tool Tip that contains the error text.
