it's actually best to draw on a Image/Bitmap and put that image on the form.

pictureBox1.Ima ge = new Bitmap(pictureB ox1.Width, pictureBox1.Hei ght);
Image bmp = pictureBox1.Ima ge;
Graphics g = Graphics.FromIm age(bmp);

//Edit bmp
g.FillRectangle (new SolidBrush(Colo r.White), 0, 0, pictureBox1.Wid th,
pictureBox1.Hei ght);
for(int I=0; I < pictureBox1.Wid th; I+)
g.DrawLine(new Pen(Color.Black ), pictureBox1.Wid th - I, 0, 0, I);

//Display bmp
pictureBox1.Ima ge = bmp;
then to save the image all you'd have to do is make the image public or
something and

bmp.SaveTo("C:\ stuff.png");

Hope that helps

// Create an image 100 x 100 pixels
Image image = new Bitmap(100, 100);

// Get the Graphics object
using (Graphics g = Graphics.FromIm age(image))
{
// Do your drawing here....
}
image.Save(file name, System.Drawing. Imaging.ImageFo rmat.Gif);
