Hello everyone,
I have a list of records, When I went to put my list in as a report data source to my rdlc report it said my datasource must be a data table or 2 other options it gave. I turned my list into a datatable and now when I insert that as my data source I get no errors and my controller action completes but my ‘return file’ never opens up a new report or anything for my record. If I try to just insert 1 record I get the report opened as an rdlc report.
            <input type="button" class="btn btn-primary" name="command" id="btnGetChecks" value="Generate Selected" />
$('#btnGetChecks').on('click', function () {
            var arrChkBoxes = [];
            var arrSelectedQIDs = [];
            var quoteid = $(this).attr("value");
            var chkboxtable = $('#maintbl');
            var chktablebody = chkboxtable.find('#maintblbody');
            $("input:checked").each(function (index, value) {
            // Push all QuoteIDs into new array
            $.each(arrChkBoxes, function (key, value) {
                if (IsPositiveInteger(value)) {

                type: "GET",
                url: "/Service/GeneratePreviewReports/",
                contentType: "application/json; charset=utf-8",
                traditional: true,
                data: { "quoteIDs": arrSelectedQIDs },
                success: function () {
                error: function (request, status, error) {
                    alert("error " + request.responseText);

        public ActionResult GeneratePreviewReports(int[] quoteIDs)
            List<ServiceQuote> lstQuotes = new List<ServiceQuote>();
            // servicequote same fields as 'Service_Fields'
            //for(int i=0; i<quoteIDs.Length-1; i++)
            //{ var quote = context.ServiceQuotes.Where(x => x.QuoteID == quoteIDs[i]).fi }
            if(quoteIDs != null)
                foreach(var qid in quoteIDs)
                    var quote = context.ServiceQuotes.Where(x => x.QuoteID == qid).FirstOrDefault();

            //TRACKER_TESTDataSetTableAdapters.Service_FieldsTableAdapter tableAdapter = new TRACKER_TESTDataSetTableAdapters.Service_FieldsTableAdapter();
            LocalReport localReport = new LocalReport()
                ReportPath = Server.MapPath("~/ReportForms/VirtualService3.rdlc")
            List<TRACKER_TESTDataSet.Service_FieldsRow> rows = new List<TRACKER_TESTDataSet.Service_FieldsRow>();

            foreach(var item in lstQuotes)
                var itemTable = CreateDT(item);//CreateDataTable(item);
                // rows.Add(tableAdapter.Fill(item))
                ReportDataSource reportDataSource = new ReportDataSource("Service_Fields", itemTable);
                // command specifies whether its a PDF EXCEL WORD IMAGE doc
                string command = "PDF";
                string reportType = command;
                string mimeType, encoding, fileNameExtension;
                string deviceInfo =
                    "<DeviceInfo>" +
                    "   <OutputFormat>" + command + "</OutputFormat>" +
                    "   <PageWidth>8.5in</PageWidth>" +
                    "   <PageHeight>11in</PageHeight>" +
                    "   <MarginTop>0.5in</MarginTop>" +
                    "   <MarginLeft>0.3in</MarginLeft>" +
                    "   <MarginRight>0.3in</MarginRight>" +
                    "   <MarginBottom>0.5</MarginBottom>" +

                Warning[] warnings;
                string[] streams;
                byte[] renderedBytes;
                renderedBytes = localReport.Render(reportType, deviceInfo, out mimeType, out encoding, out fileNameExtension, out streams, out warnings);
                return File(renderedBytes, mimeType);

            return RedirectToAction("VirtualService");

        private DataTable CreateDT(object obj)
            if(obj != null)
                Type t = obj.GetType();
                DataTable dt = new DataTable(t.Name);
                foreach(PropertyInfo pi in t.GetProperties())
                    dt.Columns.Add(new DataColumn(pi.Name));
                DataRow dr = dt.NewRow();
                foreach(DataColumn dc in dt.Columns)
                    dr[dc.ColumnName] = obj.GetType().GetProperty(dc.ColumnName).GetValue(obj, null);
                return dt;
            return null;

What I have tried:

When I have 1 record my report is displayed but now I would like multiple reports 1 for each item in the list or just 1 report with each item 1 after another in the same rdlc file. My code executes and my ajax goes to 'success' but the rdlc doesn't open.

Your action is only exporting the report for the first ID in the list. And your AJAX method isn't doing anything with the returned file. I can't see how this would ever work, even if you only selected one record.
