title: MvvmLight EventToCommand and WPFToolkit DataGrid double-click
body: <p>Trying to figure out how to use EventToCommand to set a datagrid double click handler for rows.  The command lives in the viewmodel for each row.  Just <em>that</em> much out of my experience, since I haven't used interactions yet.</p>
  
  <p>Thanks.</p>
  
  <p>I would have used mvvmlight tag, but I don't have high enough rep yet to make new tags.</p>
