  Thanks alot for your detailed reply. Following points need more assistance, as we are creating excel outputs from Web Viewer,
  
  1. How I can bind the given code on Web Viewer Export/Save options/buttons. Are you suggesting to create another button and write this Code.
  2. Taking your code will not print first occurrence of these group headers. Which is not required. Basically I want these headers not repeat on each page. Normally for Printing and viewing purpose we set Column headers / group headers to appear on each page, but on excel export this is creating problem.
  3. Even after removing headers, Fast Report create some space between pages, rather than continuous rows of data.
  
  So you valuable suggestion is required on this.

  yes, create another button and assign a function, you can place that button into built-in toolbar by injecting html tags with jquery, see attached picture.
  

  $(".frtoolbar").append('<div>[img]/content/smiley.png" onclick="alert(\'Hello World\')" height="32"></div>');

  i tried to delete object inside header/footer but it still showed out blank row with a smaller height. you may delete header/footer band, but.... in my case, i can't delete because contains a script beneath header band.
  

  using (FastReport.Report rpt = new FastReport.Report())
  {
      rpt.Load(HttpContext.Current.Server.MapPath("~/App_Data/cf.frx"));
      rpt.RegisterData(dt, dt.TableName);
      foreach (FastReport.Base obj in rpt.AllObjects)
      {
          Type type = obj.GetType();
          if (type == typeof(FastReport.GroupHeaderBand) | type == typeof(FastReport.GroupFooterBand))
          {
              FastReport.BandBase band = obj as FastReport.BandBase;
              band.Height = 0;
          }
          if (type == typeof(FastReport.TextObject))
          {
              FastReport.TextObject text = obj as FastReport.TextObject;
              if (text.HasRestriction(FastReport.Restrictions.DontMove))
              {
                  text.Delete();
              }
          }
      }
      rpt.Prepare();
      using (FastReport.Export.OoXML.Excel2007Export xl = new FastReport.Export.OoXML.Excel2007Export())
      {
          xl.Export(rpt, @"d:\test.xlsx");
      }
  }

  Can you tell me how to set UnlimitedPageHeight in FastReport.Report rpt object . This is mentioned in document but cannot find the exact property where to set. I want to set it before generating excel file. So may be I have to do nothing related to different objects.

  FastReport.Report report = new FastReport.Report();
  FastReport.ReportPage reportPage = report.Pages[0] as FastReport.ReportPage;
  reportPage.UnlimitedHeight = true;

  This is working properly and export files without page breaks. Its a better choice for this purpose.
  
  Is there any possibility or Event that we can call before Web viewers standard Export/File Save Button and set this value of Page height unlimited and after save finished restore the standard page value.
