Hi
I am using this code.

ExportOptions exportOpts = new ExportOptions();
  ExcelFormatOptions excelFormatOpts = new ExcelFormatOptions();
  DiskFileDestinationOptions diskOpts = new DiskFileDestinationOptions();
  exportOpts = _myReport.ExportOptions;
  excelFormatOpts.ExcelUseConstantColumnWidth = true; // Setting column width constant
  exportOpts.ExportFormatType = ExportFormatType.Excel;
  exportOpts.FormatOptions = excelFormatOpts;
  // Set the disk file options and export.
  exportOpts.ExportDestinationType = ExportDestinationType.DiskFile;
  diskOpts.DiskFileName = "D:\\RnD\\abc.xls";
  exportOpts.DestinationOptions = diskOpts;
  _myReport.Export();

Here I am getting columns are having constant width. But I need to maintain rows as well.
Finally I have to display constant width and rows with grid lines.

Any help appreciated!
