  <pre><code>gvExport.OptionsPrint.AutoWidth = false;
  gvExport.BestFitColumns();
  grdExport.DataSource = ds;
  
  XlsExportOptions vOptions = new XlsExportOptions();
  vOptions.TextExportMode = TextExportMode.Text;
  vOptions.ShowGridLines = true;
  vOptions.SheetName = "Test";
  
  prmFileName = "Test.xls";
