Try this:
Create a button and use this:
(for anyone else that wants to use a similar solution, TransparentPictureBox is a class that's similar to PictureBox (but not inherited) Long story, it's from a previous question by Cyber-drugs.  You should probably replace this by any control you wish to "save" to file like this:


            private void button1_Click(object sender, EventArgs e)
            {
                  System.Drawing.Graphics g = Graphics.FromHwnd(this.panel1.Handle);
                  Bitmap bmp = new Bitmap(panel1.Width, panel1.Height, g);

                  Graphics gfx;
                  Brush b = Brushes.White;
                  
                  gfx = Graphics.FromImage(bmp);
                  
                  gfx.FillRectangle(b, new Rectangle(0, 0, panel1.Width, panel1.Height));
                  foreach (TransparentPictureBox tpb in panel1.Controls)
                  {
                        gfx.DrawImage(tpb.Image, tpb.Location);
                  }
//Make this your own directory etc
                  bmp.Save(@"C:\BMPTest.bmp");

            }

Oh yes, oops. it's saving as BMP.

Replace last line by:

//C:\test.jpg, must just be what ever you want, dynamically preferbly
bmp.Save(@"C:\test.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);

you can remove the first line
System.Drawing.Graphics g = Graphics.FromHwnd(this.panel1.Handle);

Forgot to do that, was trying to do something else with this.
