David,

Setting the dgHilitedLine doesn't send selectionChanged (behavior  
mimics that of list fields). I just pasted your selectionChanged  
handler into a new data grid and tested your FindLine code to confirm.  
Did you override dgHilitedLine or are you firing off a  
selectionChanged message from somewhere else in your code?
