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

This is also the solution if (like me) you are attempting to save the Panel before the form has actually been drawn on the screen. — Chris Rae, Dec 06 '11 at 21:35
Your solution worked for me BUT controls in panels where drawn twice! So I fixed it with a IF( control is not a panel) before caling the child controls. — Christian Gold, Feb 10 '17 at 14:48

Panel1.Dock = DockStyle.None // If Panel Dockstyle is in Fill mode     
Panel1.Width = 5000  // Original Size without scrollbar     
Panel1.Height = 5000 // Original Size without scrollbar      
Dim bmp As New Bitmap(Me.Panel1.Width, Me.Panel1.Height)     
Me.Panel1.DrawToBitmap(bmp, New Rectangle(0, 0, Me.Panel1.Width, Me.Panel1.Height))     
bmp.Save("C:\panel.jpg", System.Drawing.Imaging.ImageFormat.Jpeg)      
Panel1.Dock = DockStyle.Fill

Note: Its working fine
