title: Best strategy for HTML partial rendering based on multiple dropdown values
body: <p>I have a View that renders something like this:</p>
  
  <p><img src="https://i.imgur.com/OiRvq.jpg" alt="alt text"></p>
  
  <p>"Item 1" and "Item 2" are <code>&lt;tr&gt;</code> elements from a table.</p>
  
  <p>After the user change "Value 1" or "Value 2" I would like to call a Controller and put the result (some HTML snippet) in the <code>div</code> marked as "<em>Result of...</em>".</p>
  
  <p>I have some vague notions of JQuery. I know how to bind to the <code>onchange</code> event of the <code>Select</code> element, and call the <code>$.ajax()</code> function, for example.</p>
  
  <p>But I wonder if this can be achieved in a more efficient way in ASP.NET MVC2.</p>
