title: Windows Metro App Filtering Listview and showing specific data from list?
body: <p>I am not aware if there is any "callback" to Listview creation so that i can display very specific type of data from the List i have.
  What i know is that only Complete List can be bound to the ListView, but how can i put some checking to it like its done in iOS by the help of Datasource Delegate.</p>
  
  <p>Anyone ?</p>
