title: AutoPostback from Html.Listbox in ASP.NET MVC?
body: <p>Now, i may very well just be being incredibly thick, but I'm struggling to find how to do autopostback with a Html.Listbox in ASP.NET MVC 1.</p>
  
  <p>What I'm trying to achieve is just a simple if value of ListBox1 is <em>x</em> then the values in ListBox2 are <em>y</em>, if I change the value in ListBox1 to <em>z</em> then I want the values of ListBox2 to change based off of that information.</p>
  
  <p>The information will be pulled from a Database.</p>
  
  <p>I know this is easy to in standard ASP.NET, but I can't see an obvious way to do it with MVC.</p>
  
  <p>Could someone point me in the right direction?</p>
  
  <p>Thanks in advance for any help.</p>
