How to get a winforms checkbox without text display its bottom edge?

Im currently working on a WinForms Application with VS2013 (.NET 4.5, c#) .

I'd like to use a checkbox without any label. If I empty the 'text' property the bottom edge of the cb is not displayed any more. In order to bypass that effect i tried to use a single empty space ' ' as label. Now the visual aspect is correct, but whenver the checkbox is pressed the focus switches onto the label and shows the user empty space.

Is there a more elegant way to handle that problem rather than using a custom control and set the selectable property to false?

    public class NonFocusCheckbox : CheckBox
    {
        public NonFocusCheckbox ()
        {
            SetStyle(ControlStyles.Selectable, false);
        }
    }

Note: This solution works, but seems a bit odd to be required to do that
