this may help you.

    pnlReport.AutoScrollPosition = new Point(0, 0);

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


    public void SaveBitmap(string filename)
    {
        var size = myControl.PreferredSize;
        var height = size.Height;
        Bitmap bmp = new Bitmap(this.myControl.Width, height);

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

        bmp.Save(filename, ImageFormat.Jpeg);
        bmp.Dispose();
    }
