Jeff,

I was suprised that the RowValidating event fired when I was cancelling. When the error occurs, I have 0 rows in my InvoicesItems business object and 3 rows in my DataGridView. I called Cancel() based on a keypress, so I never changed focus from the datagridview. It also happens if I move the focus away from the grid.

Are you adding new items via the business object or via the down arrow in the grid? See my warning about using the down arrow in my answer to your other post.
