        {
            if (this.Owner is VirtualizingCellsControl)
            {
                var virtualizingCellsControl = this.Owner as VirtualizingCellsControl;
                StringBuilder gridrowItems = new StringBuilder();
                var dd = virtualizingCellsControl.DataContext;
                var fontFamily = virtualizingCellsControl.FontFamily;
                var fontSize = virtualizingCellsControl.FontSize;
                gridrowItems.Append(string.Format("{0}#", fontFamily));
                gridrowItems.Append(string.Format("{0}#", fontSize));
                return gridrowItems.ToString();
