How to iterate over the rows and cells in an Xceed WPF DataGrid

I found this handy code on the Xceed forums today. See http://xceed.com/CS/forums/permalink/26496/26518/ShowThread.aspx#26518

            foreach (object item in thisDataGrid1.Items)

            {

                Dispatcher.BeginInvoke(new Action<object>(DoRow), DispatcherPriority.ApplicationIdle, item);

            }

        private void DoRow(object item)

        {

            Xceed.Wpf.DataGrid.DataRow row = this.DataGrid1.GetContainerFromItem(item) as Xceed.Wpf.DataGrid.DataRow;

            if (row != null)

            {

                foreach (Xceed.Wpf.DataGrid.DataCell c in row.Cells)

                {

                    if (c != null)

                    {

                        //Do something to the cell

                    }

                }

            }

        }
