How can I prevent the user from clicking off the cell they are editing, until they either press return or ESC. Thanks,

Try handling these two events using the added lastKeyDown field.
 
private Keys lastKeyDown = Keys.None;

private void gridControl1_CurrentCellKeyDown(object sender, KeyEventArgs e)
{
    this.lastKeyDown = e.KeyCode;
}
private void gridControl1_CurrentCellValidating(object sender, CancelEventArgs e)
{
    if(lastKeyDown != Keys.Enter && lastKeyDown != Keys.Escape)
        e.Cancel = true;
}
