title: C# redrawing graphics on winform
body: <p>I have a bitmap loaded onto a winform via an imagebox.  When I want to update the image I try as such:</p>
  
  <pre><code>imagebox.image = null;
  draw();  //implements the drawing of the bitmap and assigns to the imagebox/winform
  </code></pre>
  
  <p>However, this will only work if I hide and then show the form again?  How can I get around this?</p>
  
  <p>EDIT:  Problem resolved.</p>
