Create a PDF file on button press in browser

When you use the FastReport .Net together ASP.Net MVC framework you have easy method for creating file in any supported format on button press in HTML form.

Add next code in View:

 @using (Html.BeginForm("GetFile", "Home"))
 {
         <input id="pdf" type="submit" value="Export to PDF" />
 }

GetFile - name of controller handler, Home - name of controller (HomeController.cs for example)

Add name space in controller:

using FastReport.Export.Pdf;

Add method GetFile in controller:

        public FileResult GetFile()
        {
            WebReport webReport = new WebReport();

            // bind data
            System.Data.DataSet dataSet = new System.Data.DataSet();
            dataSet.ReadXml(report_path + "nwind.xml");
            webReport.Report.RegisterData(dataSet, "NorthWind");
           
            // load report
            webReport.ReportFile = this.Server.MapPath("~/App_Data/report.frx");

            // prepare report
            webReport.Report.Prepare();

            // save file in stream
            Stream stream = new MemoryStream();
            webReport.Report.Export(new PDFExport(), stream);
            stream.Position = 0;

            // return stream in browser
            return File(stream, "application/zip", "report.pdf");
        }

Example for Excel 2007:

using FastReport.Export.OoXML;
...
webReport.Report.Export(new Excel2007Export(), stream);
...
return File(stream, "application/xlsx", "report.xlsx");
