Question

Which event fires when DataGrid’s source is updating? I’ve tried DataContextChanged and SourceUpdated but it never worked out.

Actually I need a simple thing. I want, if there is a new row comes, scroll the GridView’s scrollbar down to the bottom to see what it was.

I had the same problem and I manage it this way

DataGrid myGrid = new DataGrid();
CollectionView myCollectionView = (CollectionView)CollectionViewSource.GetDefaultView(myGrid.Items);
((INotifyCollectionChanged)myCollectionView).CollectionChanged += new NotifyCollectionChangedEventHandler(DataGrid_CollectionChanged);

You then need to implement the logic in the event handler DataGrid_CollectionChanged.
