        if (mainDataGrid.Items.Count > 0)
        {
            var border = VisualTreeHelper.GetChild(mainDataGrid, 0) as Decorator;
            if (border != null)
            {
                var scroll = border.Child as ScrollViewer;
                if (scroll != null) scroll.ScrollToEnd();
            }
        }
