How can I get scrollbars on Picturebox

I have PictureBox picture.

I use:

picture.Size = bmp.Size;
picture.Image = bmp;

Let's say there are two integers maxWidth and maxHeigth.
I want to add vertical/horizontal scrollbar to picture when its size exceeds maxWidth and/or maxHeight. How can I do that?

You can easily do it with a Panel Control

Insert a panel to your form, say panel1 and set

panel1.AutoScroll = true;

insert a PictureBox to the Panel, say picture and set

picture.SizeMode = PictureBoxSizeMode.AutoSize;

and set the Image

picture.Image = bmp;

It works to me.

PictureBox picture = new PictureBox();
picture.Image=Image.FromFile("image.bmp");
picture.SizeMode = System.Windows.Forms.PictureBoxSizeMode.AutoSize;
Panel panel = new Panel();
panel.Size=new Size(800,600);
panel.Location=new Point(0,0);
panel.AutoScroll=true;
panel.Controls.Add(picture);
this.Controls.Add(panel);

I got it to work by also putting a picturebox inside a panel control, I set the Panel's AutoScroll property to true, but I also set the Panel's Autosize property to True, and the Panel's Dock property to Fill (that way when the user resizes the form - so will the Panel). For the Picturebox, I set it's Dock property to None, and the SizeMode to Autosize (so it resizes also when the Panel and form Resizes. It worked like a charm, the Picturebox has Scrollbars and when the user resizes the form - everything is still placed correctly!

Another suggestion is to put the picturebox inside a FlowlayoutPanel .

Set the Auto scroll of the FlowlayoutPanel to true and set the picture size mode to normal

Using a FlowlayoutPanel makes sure the image is always at 0,0 in the panel

Here's a project where a guy built an ImagePanel user control that you can drop onto a form; it gives you scrollbars and zoom capability.
