Partially fill a Rectangle object

Question

I was wondering if it's possible to fill a certain percentage of a Rectangle object that's been draw on-screen so that it behaves like a Progress Bar, where you can watch its "level" go up and down. Specifically, I'd like to fill it from top to bottom rather than left to right.

You can try this.

private void button1_Click(object sender, EventArgs e)
{
    panel1.Width = 400;
    panel1.Height = 50;

    using (Graphics g = this.panel1.CreateGraphics()) 
    {
        g.Clear(Color.Black);
        Pen pen = new Pen(Color.Red, 2);               
        for (int i = 0; i <= 50;i++ )
        {
            g.DrawRectangle(pen, 0, 0, 400, i);                    
            Thread.Sleep(100);
        }                   
        pen.Dispose();
    }
}
