关键代码：

        /// <summary>        /// 根据rowIndex和visibleColumnsIndex来获取单元格可见值        /// </summary>        /// <param name="view">GridView</param>        /// <param name="rowIndex">rowIndex</param>        /// <param name="visibleColumnsIndex">visibleColumnsIndex</param>        /// <returns>单元格可见值</returns>        public static string GetRowCellDisplayText(this GridView view, int rowIndex, int visibleColumnsIndex)        {            return view.GetRowCellDisplayText(rowIndex, view.VisibleColumns[visibleColumnsIndex]);        }        /// <summary>        /// 根据rowIndex和visibleColumnsIndex来获取单元格值        /// </summary>        /// <param name="view">GridView</param>        /// <param name="rowIndex">rowIndex</param>        /// <param name="visibleColumnsIndex">visibleColumnsIndex</param>        /// <returns>单元格值</returns>        public static object GetRowCellValue(this GridView view, int rowIndex, int visibleColumnsIndex)        {            return view.GetRowCellValue(rowIndex, view.VisibleColumns[visibleColumnsIndex]);        }
