title: Silverlight listbox binding question
body: <p>I have a list which is bound to an observable collection of custom class. Works perfect. </p>
  
  <p>What I want to do us add a row in the last which is not a part of observable collection whenever it comes into view it should trigger a function to load more items in to listbox. </p>
  
  <p>Thanks
