Saving Panel as JPEG, only saving visible areas c#

Question

I'm trying to save, and then print a panel in c#. My only problem is that it only saves the visible areas and when I scroll down it prints that.

 Bitmap bmp = new Bitmap(this.panel.Width, this.panel.Height);

 this.panel.DrawToBitmap(bmp, new Rectangle(0, 0, this.panel.Width, this.panel.Height));

 bmp.Save("c:\\panel.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);

Try following

    public void DrawControl(Control control,Bitmap bitmap)
    {
        control.DrawToBitmap(bitmap,control.Bounds);
        foreach (Control childControl in control.Controls)
        {
            DrawControl(childControl,bitmap);
        }
    }

    public void SaveBitmap()
    {
        Bitmap bmp = new Bitmap(this.panel1.Width, this.panel.Height);

        this.panel.DrawToBitmap(bmp, new Rectangle(0, 0, this.panel.Width, this.panel.Height));
        foreach (Control control in panel1.Controls)
        {
            DrawControl(control, bmp);
        }

        bmp.Save("d:\\panel.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
    }

Here is my result:

Form ScreenShot :

Saved bitmap :

As you can see there is TextBox wich is not visible on form but is present in saved bitmap
