RDLC Data Error

Question

User-952930563 posted

Hi everyone,

I am new with ASP.net and i'm trying to make an easy application.

I want to make a RDLC report after someone made a reservation.

This is my code for convert to PDF and my ASPXPage:

    public ActionResult Reports(string ReportType, int reportId)
    {

        LocalReport localreport = new LocalReport();
        localreport.ReportPath = Server.MapPath("~/Reports/Report_Reservatie.rdlc");

        ReportDataSource reportDataSource = new ReportDataSource();
        reportDataSource.Name = "DataSet_Reservaties";
        reportDataSource.Value = storeDB.Reservaties.FirstOrDefault(a => a.ReservatieId == reportId);

        localreport.DataSources.Add(reportDataSource);

        string reportType = ReportType;
        string mimeType;
        string encoding;
        string fileNameExtension;

        if (reportType == "PDF")
        {
            fileNameExtension = "pdf";
        }
        else
        {
            fileNameExtension = "jpg";
        }
        string[] streams;
        Warning[] warnings;
        byte[] renderedByte;
        renderedByte = localreport.Render(reportType, "", out mimeType, out encoding, out fileNameExtension, out streams, out warnings);
        Response.AddHeader("content-disposition", "attachment:filename + reservaties_report." + fileNameExtension);
        return File(renderedByte, fileNameExtension);
    }
}

@model int
@{
ViewBag.Title = "Checkout Complete";
}
<h2>@MyApplication.Resources.ResourceNL.CheckoutComplete</h2>
<p>@MyApplication.Resources.ResourceNL.ThankForTheOrder: @Model</p>

@Html.ActionLink("Export to PDF", "Reports", new { ReportType = "PDF",}, null)

But now i always get this error:

The parameters dictionary contains a null entry for parameter 'reportId' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Reports

Can someone please help me en tell me how to solve this? Did i forgot something?

Thanks!!

Hi Benzo,

The error says that Report_ID contains null value.

Please try to check what value is passing for Report_ID at run time.

If it is null then try to pass proper value for Report_ID to solve the error.

If issue persist then let us know about that.

We will try to provide further suggestions to solve the issue.
