title: How to Make a PictureBox Scrollable
body: <p>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".</p>
  
  <ol>
  <li>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.</li>
  </ol>
  
  <p>How can I make it? Any example for this thread?</p>
  
  <p>My Best Regards...</p>
