title: ASP.NET - Hierarchical grid view
body: <p>Any ideas on how I can acheive 'Hierarchical' gridview?
  Basically I want when the user clicks on the '+', i "expand" and insert new rows without a full page post back. </p>
  
  <p>Does this sound like a lot of AJAX stuff? Or should I read on ASP.NET MVC</p>
  
  <p>Please point me in right direction</p>
