How to print panel in windows form?

Question

I Have windows form but i want to print panel in windows form to hidden print button and it's my code :

   private void printDoc_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
    {
        System.Drawing.Image image = System.Drawing.Image.FromStream(this.streamToPrint);
        int x = e.MarginBounds.X;
        int y = e.MarginBounds.Y;
        int width = image.Width;
        int height = image.Height;
        if ((width / e.MarginBounds.Width) > (height / e.MarginBounds.Height))
        {
            width = e.MarginBounds.Width;
            height = image.Height * e.MarginBounds.Width / image.Width;
        }
        else
        {
            height = e.MarginBounds.Height;
            width = image.Width * e.MarginBounds.Height / image.Height;
        }
        System.Drawing.Rectangle destRect = new System.Drawing.Rectangle(x, y, width, height);
        e.Graphics.DrawImage(image, destRect, 0, 0, image.Width, image.Height, System.Drawing.GraphicsUnit.Pixel);
    }

    public void StartPrint(Stream streamToPrint, string streamType)
    {
        this.printDoc.PrintPage += new PrintPageEventHandler(printDoc_PrintPage);


        this.streamToPrint = streamToPrint;
        this.streamType = streamType;
        System.Windows.Forms.PrintDialog PrintDialog1 = new PrintDialog();
        PrintDialog1.AllowSomePages = true;
        PrintDialog1.ShowHelp = true;
        PrintDialog1.Document = printDoc;

        DialogResult result = PrintDialog1.ShowDialog();
        if (result == DialogResult.OK)
        {
            printDoc.Print();
            //docToPrint.Print();
        }

    }

    private void button_Print_Certificate_Click(object sender, EventArgs e)
    {
          Graphics g1 = this.CreateGraphics();
        Image MyImage = new Bitmap(this.ClientRectangle.Width,      this.ClientRectangle.Height, g1);
        Graphics g2 = Graphics.FromImage(MyImage);
        IntPtr dc1 = g1.GetHdc();
        IntPtr dc2 = g2.GetHdc();
        BitBlt(dc2, 0, 0, this.ClientRectangle.Width, this.ClientRectangle.Height, dc1, 0, 0, 13369376);
        g1.ReleaseHdc(dc1);
        g2.ReleaseHdc(dc2);
        MyImage.Save(@"D:\PrintPage.jpg", ImageFormat.Jpeg);
        FileStream fileStream = new FileStream(@"D:\PrintPage.jpg", FileMode.Open, FileAccess.Read);
        StartPrint(fileStream, "Image");
        fileStream.Close();

        if (System.IO.File.Exists(@"D:\PrintPage.jpg"))
        {
            System.IO.File.Delete(@"D:\PrintPage.jpg");
        }
    }

So what's the question? How is the panel you mentioned in your title related? What is the difference between what the code you posted does and what you want? — Ben Voigt, Apr 18 '14 at 19:57

Try replacing all occurrences of `this` in `button_Print_Certificate_Click` with the panel object. — Ben Voigt, Apr 18 '14 at 20:04
Ok, I've turned that idea into an actual answer. Is everything working correctly now> — Ben Voigt, Apr 18 '14 at 20:17

In order to print a particular control, you'll want to use that control as the source of your BitBlt operation.

So instead of this.CreateGraphics(), call panel.CreateGraphics(). Similarly, use panel.ClientRectangle to get the width and height of the image.

But take a look at https://stackoverflow.com/a/597088/103167 which gives you an easier way.
