C#: ProgressBar with percentage

[kisjaksi]

I made a progressbar-control, which is supposed to write the percentage in the middle of the progressbar, but it doesn't work. Why?!

    class PProgressBar : ProgressBar
    {
        public PProgressBar()
            : base()
        {
        }

        protected override void OnPaint(PaintEventArgs e)
        {
            base.OnPaint(e);
            e.Graphics.DrawString((100 * this.Value / this.Maximum).ToString(), new Font("Arial", 8.25f), Brushes.Black, new PointF(this.Size.Width / 2 - 10, this.Size.Height / 2 - 8));
        }
    }

Turns out that M$ decided to seal the ProgressBar class, but not in such a way that it would throw an exception when you try to inherit from it (or when you check IsSealed, for that matter). Regardless, M$, in their own words, say the progressbar class is sealed, and so it'll never even call the OnPaint event when overriden.

There are some places that say you can still override if you use SetStyle in the constructor, but all I saw then was the text w/ no bar.

There's a tutorial by M$ titled something like "How to build smooth progress bars" which let's you create your own progress bar control on which you can override the OnPait event w/ your changes.
