private void dgv_Scroll(object sender, ScrollEventArgs e)
        {
            if (e.OldValue > e.NewValue)
            {
                // here up
            }
            else
            {
                // here down
            }
        }

Use the passed System.Windows.Forms.ScrollEventArgs arguments' OldValue and NewValue properties to detect the scroll direction.
