When a user wants to delete a row in a DGV, they are asked if they are sure they want to do it.

My question is how do I go about stopping the row from being deleted should they say no?

Code:
Private Sub RoomCodesDGV_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles RoomCodesDGV.KeyDown

        Select Case e.KeyCode
            Case Keys.Delete

                If MsgBox("Are You Sure That You Want To Delete This Line?     ", MsgBoxStyle.Question & MsgBoxStyle.YesNo, "Delete Room Code") = MsgBoxResult.No Then

                   ??????

                End If

        End Select
End Sub
Any help would be appreciated.
