Automatically Resize Form?

[zacks@construction-imaging.com]

I am developing an application in VS2005. I have a form that has a
PictureBox control whose purpose is to be able to plop a User Control
in it. And the User Control can be one of several possible User
Controls and these User Controls are all different in size, some
larger that the picture box it will be added to.

How do I get the form to resize when I add a User Control to the
picture box control when the User Control is larger than the picture
box?

Why are you using a PictureBox? That's wholly inappropriate as a
container control.

If you were using a proper container control, you'd have the AutoSize and
AutoSizeMode properties that would allow you to do this automatically.
Just set AutoSize to true and AutoSizeMode to AutoSizeMode.Gr owAndShrink.
Then as items are added or removed from the control, it will resize
appropriately.

Not "automatic" but it has the distinct advantage of working.

picturebox.Cont rols.Clear();

this.Width = this.Width + (usercontrol.Wi dth - picturebox.Widt h);

picturebox.Widt h = usercontrol.Wid th;
picturebox.Cont rols.Add(userco ntrol);
this.CenterToSc reen();

But again, why are you using a PictureBox? Why not use a more appropriate
control that already implements this automatic behavior?

Even if you want a PictureBox in there somewhere, for the purpose of
displaying an image, there's no need to make the PictureBox the container
itself. Use a real container, and put into it both the PictureBox and
your UserControl. You can even have the PictureBox anchored so that it
resizes as necessary as the container resizes according to the size of the
UserControl. And depending on how you want the image displayed, you could
simply set the background image for the container control and not bother
with a PictureBox at all.

You seem to be implementing very awkward code for no good reason. At the
very least, if there's really a good reason for using a PictureBox, it
would help to understand your question better if you could explain what
that reason is.

What control would be a "proper container control"? Panel?
