title: WPF DataGrid - Event for New Rows?
body: <p>I'm using the WPF <code>DataGrid</code> (<strong>.Net 3.5 SP 1</strong> version from the <a href="http://wpf.codeplex.com/releases/view/40535" rel="noreferrer">Toolkit</a>)</p>
  
  <p>What event can I subscribe to, to detect when a new row is added? (e.g. when the user moves the cursor down or presses Enter a new blank row gets added to the grid).</p>
  
  <p>Eventually what I want to do is use that event to calculate some default values and put them in the new row.</p>
  
  <p>The grid is bound to a <code>DataTable</code>, if that makes any difference.</p>
