Print problem

I have a PictureBox on a form. I have set up a print routine to send the
image to a printer, basically copied out of Help, with a
'e.Graphics.DrawImageUnscaled(PictureBox1.Image, 0, 0)' call in the
PrintPage event handler. The image prints ok.

One complication. This particular picturebox has a number of custom
controls sitting on it with the picture box defined as their parent. They
are not showing up in the print. How do I include them?

Hi,

this is kinda difficult to do. I recently built a similar application,
using an image as a map and pins on them which were controls. You will
have to manually paint the controls onto the Graphics object passed to
you in the event arguments. This is difficult because you need to take
scaling and such into account. You can add a Print method to your
custom controls from the Print method you can then call OnPaint using a
PaintEventArgs constructed by hand. I do not know for sure if this will
work for the default WinForms controls

I kind of suspected that. I'll just have to experiment.

Thanks!

Try using the PrintWindow method to print directly to a bitmap. You may find
this works but I suspect that the controls on top of the picturebox are
siblings of the PB rather than children. Am I right?

If this is the case you may have to make all the controls children of a
Panel and call PrintWindow with the Panel's window handle.

Actually no. The Parent property of every control is set to the picturebox.
