Finding a DataGridRow based on row index in WPF

        private static DataGridRow GetRow(DataGrid grid, int index)
        {
            var row = (DataGridRow)grid.ItemContainerGenerator.ContainerFromIndex(index);
            if (row == null)
            {
                // May be virtualized, bring into view and try again.
                grid.UpdateLayout();
                if (index >= grid.Items.Count)
                {
                    index = grid.Items.Count - 1;
                }

                grid.ScrollIntoView(grid.Items[index]);
                row = (DataGridRow)grid.ItemContainerGenerator.ContainerFromIndex(index);
            }
            return row;
        }
