title: Temporarily switch off bindings in WPF
body: <p>The title of the question is bad, feel free to update it. </p>
  
  <p>I have an observablecollection that generates a user control whenever it an item has been added to it. 
  However there are times where I just want to add to the collection and not have it create a usercontrol. Is there a way around this problem? Thanks.</p>
