How to Make a PictureBox Scrollable [duplicate]

Question

I've 2 buttons, 1 PictureBox and 1 Panel. PictureBox's inside of the Panel and Panel's AutoScroll property is set to "true". Also PictureBox Dock property is set to "Fill".

1. Button draws a Rectangle into the pictureBox, 2. one makes it bigger whose size is bigger than the pictureBox itself. So, I need pictureBox to be scrollable.

How can I make it? Any example for this thread?

My Best Regards...

1- Set your panel's AutoScroll property to true:

this.panel1.AutoScroll = true;  

2- Set SizeMode property of your picturebox to AutoSize:

this.pictureBox1.SizeMode = System.Windows.Forms.PictureBoxSizeMode.AutoSize;  

That should do the trick.
If you still have problems, there are some workaround mentioned in the following pages:

To do that, you need to change the PictureBox's Dock to None, then set the size yourself.
