Hi again,
I am trying to connect a report to go directly to PDF in MVC2
I found code online
 public ActionResult RemarksReport(int id)       
         {  
             LocalReport localReport = new LocalReport();            
             localReport.ReportPath = Server.MapPath("~/Reports/RemarksReport.rdlc");
             ReportDataSource reportDataSource = new ReportDataSource("RemarksData", rr.GetRemarksReport(id)); 
             localReport.DataSources.Add(reportDataSource);            
             string reportType = "PDF";            
             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>PDF</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;             
             //Render the report            
             renderedBytes = localReport.Render(                
                 reportType,                
                 deviceInfo,                
                 out mimeType,                
                 out encoding,                
                 out fileNameExtension,                
                 out streams,                
                 out warnings);            
             //Response.AddHeader("content-disposition", "attachment; filename=NorthWindCustomers." + fileNameExtension);            
             return File(renderedBytes, mimeType);        
            
         }
    }
}

Open in new window

and a datasource
    public IList<RemarksReport> GetRemarksReport(int id)
    {
        var result = db.REPORT_Remarks(id);
        return ( from r in result
            select new RemarksReport
            {
                Date = r.DATE,
                FullName = r.FULLNAME,
                Type = r.TYPE,
                Notes = r.NOTES
            }).ToList();
            }

Open in new window


I can step through it and watch reportDatasource filling up but when it gets to the report its as if it can't see the data.
I get the error
A data source instance has not been supplied for the data source "RemarksReport"

The website I was using http://weblogs.asp.net/rajbk/archive/2009/11/25/rendering-an-rdlc-directly-to-the-response-stream-in-asp-net-mvc.aspx
showing how to generate a report without a dataset.

If anymore info is needed just let me know.

Thank you in advance

The only thing I can think of at this moment is that the data source name in the report is different than the name of ReportDataSource--RemarksData.

I have made the changes so the names match but still getting errors, again I can watch the data source filling up but then when it gets to the report it seems there is nothing there

Something I did, just in case it makes a difference I am changed the ActionLink in the website used to open the report to a type button calling a jquery function

@TheLearnedOne.
Thanks when you told me to send you the rdlc file I was attaching it and thought I would open it as xml and noticed it was still using the other data source. When I changed it, it now runs to the end but I get a different error. Actually a jQuery error. (.PDF is not a function) which is caused by a completely different problem (I think) so thank you for putting me on the right track

The comments made especially when TheLearnedOne was looking to see my .rdlc file made me look at it in xml when I did this I seen the file was pointing to the wrong datasource
