I have two separate projects MyApp.Reports and MyApp.WEB

the MyApp.Reports containts only *.rdlc reports and MyApp.WEB is the ASP.NET MVC 4 Razor. I have a requirement to export the data from my report to Excel and let the user Download it, how can i load the data from my model to the Report and export it to an Excel file?

What i allready tried:

Prototype MVC4 Razor ReportViewer? RDLC <-- Generates an image instead of PDF or Excel

Model:

public class MyModel
{
  public int OrderNr { get; set;}
  public string Title { get; set;}
}

Action:

    public ActionResult ExportToExcel()
    {
      IEnumerable<MyModel> model = database.GetMyModelData(); //<-- returns list of data 
      ...
    }

"P.S. this is not a duplicate" - show exactly what you found and why you think that didn't apply. See for example Creating a Custom Export to Excel for ReportViewer (rdlc).CodeCaster
Your link uses report viewer from webforms as a said i want the user to see a download and in razor is there a way to not use webforms?AirWolf
Here is a CodeProject page on using local ssrs reports from MVC. codeproject.com/Articles/609580/…Bradley Uffner
Ill look at that once i get home thanksAirWolf
Looks like your suggested link uses report to generate an Image, and even when i downloaded the sample and clicked on view as PDF it gives me an image and that's it, any more ideas would be appreciatedAirWolf

After tinkering with the CodeProject demo that "Bradly Uffner" gave me i managed to get the code working the way i wanted it to, you can download the demo project Here. So here is what i came up with:

View:

@Html.ActionLink("Download Report in Excel Format", "ExportReport", new { ContentType = "application/vnd.ms-excel", FileType = "Excel" })

@Html.ActionLink("Download Report in PDF Format", "ExportReport", new { ContentType = "application/pdf", FileType = "pdf" })

Controller:

public ActionResult ExportReport(string FileType, string ContentType)
{
    LocalReport localReport = new LocalReport();
    localReport.ReportPath = Server.MapPath("~/Content/Report1.rdlc");
    IList<WorldModel> customerList = new List<WorldModel>();

    // SOME DEMO DATA!
    customerList.Add(new WorldModel("Europe", "Sweden", "2001", "1823"));
    customerList.Add(new WorldModel("Europe", "Sweden", "2002", "1234"));
    customerList.Add(new WorldModel("Europe", "Sweden", "2003", "9087"));

    customerList.Add(new WorldModel("Europe", "Denmark", "2001", "6793"));
    customerList.Add(new WorldModel("Europe", "Denmark", "2002", "4563"));
    customerList.Add(new WorldModel("Europe", "Denmark", "2003", "1897"));

    customerList.Add(new WorldModel("Europe", "Norway", "2001", "5632"));
    customerList.Add(new WorldModel("Europe", "Norway", "2002", "9870"));
    customerList.Add(new WorldModel("Europe", "Norway", "2003", "2367"));

    customerList.Add(new WorldModel("Asia", "India", "2001", "1980"));
    customerList.Add(new WorldModel("Asia", "India", "2002", "9765"));
    customerList.Add(new WorldModel("Asia", "India", "2003", "6789"));
    //DEMO DATA END

    ReportDataSource reportDataSource = new ReportDataSource();
    reportDataSource.Name = "DataSet1";

    //********** IF YOU NEED TO FILTER THE DATA ******************
    //var customerfilterList = from c in customerList
    //                         where c.Territory == territory
    //                         select c;
    //reportDataSource.Value = customerfilterList;
    //************************************************************

    reportDataSource.Value = customerList;

    localReport.DataSources.Add(reportDataSource);
    string reportType = FileType;
    string mimeType;
    string encoding;
    string fileNameExtension;
    //The DeviceInfo settings should be changed based on the reportType            
    //http://msdn2.microsoft.com/en-us/library/ms155397.aspx            
    string deviceInfo = "<DeviceInfo>" +
        "  <OutputFormat>" + FileType + "</OutputFormat>" +
        "  <PageWidth>8.5in</PageWidth>" +
        "  <PageHeight>11in</PageHeight>" +
        "  <MarginTop>0.5in</MarginTop>" +
        "  <MarginLeft>1in</MarginLeft>" +
        "  <MarginRight>1in</MarginRight>" +
        "  <MarginBottom>0.5in</MarginBottom>" +
        "</DeviceInfo>";
    Warning[] warnings;
    string[] streams;
    byte[] renderedBytes = localReport.Render(reportType, deviceInfo, out mimeType, out encoding, out fileNameExtension, out streams, out warnings);          
    return File(renderedBytes, ContentType, string.Format("NameOfFile.{0}",fileNameExtension));

}

I'm not sure if this will work if the reports are in a seperate project but i will try that also.
