title: Silverlight and icollectionview
body: <p>So I have a datagrid that I need to add custom sorting for and I also need to know the exact order of the sort.</p>
  
  <p>I have read in order to do this I need to implement a custom icollectionview and bind it to the datagrid.</p>
  
  <p>The problem I am having is that the documentation Microsoft gives on this interface is not that great.  Does anyone know how to do this or have any good tutorials on how to implement this interface for silverlight?</p>
