title: Getting at the Listbox's ItemContainer when data binding
body: <p>Is there a way to get at the ItemContaner of a selected item in a listbox?  In Silverlight 2.0 Beta 1 I could, but the container is hidden in Beta 2 of Silverlight 2.0. </p>
  
  <p>I'm trying to resize the listbox item when it is unselected to a specific size and when selected to a variable size.  I also want to get the relative position of the selected item for animations.   Growing to a variable size and getting the relative pasition is why i need to get to the listbox item.</p>
  
  <p>I should clarify i'm not adding items to the listbox explicitly.  I am using data binding in xaml and DataTemplates.  What I have trouble accessing is the ItemContainer of the selected item's DataTemplate.</p>
