如何打印Winforms用户控件

Question

I've created a winforms usercontrol doing a lot of custom painting in the OnPaint event. Now I would like to print this control.

• is there a wysiwyg method to position this control on 'a document' and print the document including the usercontrol ?

or

• when using printpage() event of a printdocument, can I dynamically create & position my usercontrol on the 'page' and somehow call the paint method of my usercontrol ?

In PrintPage event aquire image of control, and draw it to printer graphics.

private void PrintPageEventHandler(object sender, PrintPageEventArgs ev) {
            Rectangle rect = new Rectangle(0, 0, yourControl.Width, yourControl.Height);

            //aquire image of yourControl
            Bitmap bitmap = new Bitmap(yourControl.Width, yourControl.Height);     
            yourControl.DrawToBitmap(bitmap, rect);

            ev.Graphics.DrawImage(bitmap, new Point(0, 0)); //place image on right position istead of (0, 0)

}
