Write report to disk

Jun 20, 2012 at 9:44 AM


Using Doddle MVC ReportResult() is there a way to write the generated report to the web server hard disk instead of serving it to the client?

I'd like to pre-publish reports for the user as some of my reports can take a long time to pull their required data!

Just though i would give this a nudge - has ANYONE got any suggestions for this?

Hi fillus, i don't know if this helps

public ActionResult Index()
            string file = @"C:\......."
            var query = DoddleProductRepository.GetAll();
            var totalProducts = query.Count;
            var totalOrders = query.Sum(p => p.OrderCount);

            // Create the report and turn our query into a ReportSource
            var report = new Report(query.ToReportSource());

            // Customize the Text Fields
            report.TextFields.Title = "Products Report";
            report.TextFields.SubTitle = "This is a sample report showing how Doddle Report works";
            report.TextFields.Footer = "Copyright 2011 (c) The Doddle Project";
            report.TextFields.Header = string.Format(@"
                Report Generated: {0}
                Total Products: {1}
                Total Orders: {2}
                Total Sales: {3:c}", DateTime.Now, totalProducts, totalOrders, totalProducts * totalOrders);

            IReportWriter writer = new DoddleReport.OpenXml.ExcelReportWriter();

            using (FileStream fs = new FileStream(file, FileMode.Create))
                writer.WriteReport(report, fs);

            return View();
It's just an idea. You generate the report as you always do but you don't return a ReportResult, you write the report to de server HD and then you return a view or whatever you want informing the report was generated. Is it what you nedeed??? (Sorry for my english)

Thanks for helping out Snekkke, your solution is indeed correct. The IReportWriter's can write to any Stream instance. If you open a FileStream you can tell the Writer to push it's data to it, which would create the file.


In the source code there is a DoddleReport.Sample.WinForms which shows this idea:

            using (var stream = File.Create("Report.xlsx"))
