title: MVC3 Razor Html.TextBoxFor Calculated Fields
body: <p>Ultimately I would like to have calculated fields like Weight * Price.</p>
  
  <p>Suppose I have in my MVC3 view:</p>
  
  <pre><code>    @Html.TextBoxFor(modelItem =&gt; item.Package.USDKg)
      @Html.HiddenFor(modelItem =&gt; item.Pricing.VolumePrice)
  </code></pre>
  
  <p>Am I able to calculate these directly? Or resort to JQuery?
  I would really like to keep pricing "hidden" even in source view if possible.</p>
  
  <p>Basically, when a user enters their package weight, a price would be displayed (calculated off of hidden price point values).</p>
  
  <p>Thank you for your guidance.</p>
