Load Workbook created in C# Excel Engine
posted

I have created a workbook using the c# infragistics excel engine, I have tried several methods to populate the igSpreadsheet with the workbook.

my Controller:

public void GetReport()
   {
                    var test= ReportHelper.GetRentRollExcel(new RentRollExcel
               {
                   CurrentDatePicker =  DateTime.UtcNow,
                   Id = 9,
                   SendForDownload = false
               }, _db, Server.MapPath("~"), Url, false);
 
       Response.Clear();
       Response.AppendHeader("content-disposition", "attachment; filename=" + test.FileName);
       Response.ContentType = "application/octet-stream";
       test.Workbook.Save(Response.OutputStream);
       Response.End();
   }
  

 public FileContentResult GetReport2()
   {
 
 
       MemoryStream fs = new MemoryStream();
       var test = ReportHelper.GetRentRollExcel(new RentRollExcel
       {
           CurrentDatePicker = DateTime.UtcNow,
           Id = 9,
           SendForDownload = false
       }, _db, Server.MapPath("~"), Url, false);
 
      
       test.Workbook.Save(fs);
 
       return new FileContentResult(fs.ToArray(), "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
 
   }

public string GetReport3()
     {
 
 
         MemoryStream fs = new MemoryStream();
         var test = ReportHelper.GetRentRollExcel(new RentRollExcel
         {
             CurrentDatePicker = DateTime.UtcNow,
             Id = 9,
             SendForDownload = false
         }, _db, Server.MapPath("~"), Url, false);
 
 
         test.Workbook.Save(fs);
         return BitConverter.ToString(fs.ToArray());
         return Convert.ToBase64String(fs.ToArray());
         
     }

Obviously I have tried different ways to accomplish this: In the Java Script I have:

tried the following:

         $.ig.loader({
        scriptPath: "/Scripts/Infragistics/",
        cssPath: "/Content/InfragisticsCSS/css",
        resources: "igSpreadsheet, igExcel.LoadSaveXlsx, igExcel.LoadSaveXls, igExcel.Functions",
        ready: function() {
                    //Initializing igSpreadsheet
            $("#spreadsheet").igSpreadsheet({
                height: "600",
                width: "100%",
                isFormulaBarVisible: false,
                allowAddWorksheet: false,
                allowDeleteWorksheet: false
            });
            var workbook = null;
            var xhr = new XMLHttpRequest();
            xhr.open('GET', '@Url.Action("GetReport3", "Reports")', true);
            xhr.responseType = 'blob';
 
            xhr.onload = function (e) {
                        // response is unsigned 8 bit integer
 
                var fileReader = new FileReader();
 
 
                fileReader.onload = function (e) {
 
                  
                    var buffer = new Uint8Array(fileReader.result);
                    $.ig.excel.Workbook.load(buffer,
                        function(arg) {
                            workbook = arg;
                            setInitialSettings();
                        },
                        function() {
                            console.log("fail");
                        });
                }
                fileReader.readAsArrayBuffer(this.response);
 
 
            };
            xhr.send();
 
        }
    });
 
 
    $('#CompanyEntityId').selectize();
 
 
})

//Another ATTEMPT
          $.ig.loader({
              scriptPath: "/Scripts/Infragistics/",
              cssPath: "/Content/InfragisticsCSS/css",
              resources: "igSpreadsheet, igExcel.LoadSaveXlsx, igExcel.LoadSaveXls, igExcel.Functions",
              ready: function() {
                    //Initializing igSpreadsheet
                  $("#spreadsheet").igSpreadsheet({
                      height: "600",
                      width: "100%",
                      isFormulaBarVisible: false,
                      allowAddWorksheet: false,
                      allowDeleteWorksheet: false
                  });
                  var workbook = null;
                  var xhr = new XMLHttpRequest();
                  xhr.open('GET', '@Url.Action("GetReport", "Reports")', true);
                  xhr.responseType = 'blob';
 
                  xhr.onload = function(e) {
                        // response is unsigned 8 bit integer
 
                      var fileReader = new FileReader();
 
 
                      fileReader.onload = function(e) {
                          var buffer = new Uint8Array(fileReader.result);
                          $.ig.excel.Workbook.load(fileReader.result,
                              function(arg) {
                                  workbook = arg;
                                  setInitialSettings();
                              },
                              function() {
                                  console.log("fail");
                              });
                      }
                      fileReader.readAsArrayBuffer(this.response);
 
 
                  };
                  xhr.send();
 
              }
          });
 
 
          $('#CompanyEntityId').selectize();
 
 
      });

            //Another ATTEMPT
    $.ig.loader({
        scriptPath: "/Scripts/Infragistics/",
        cssPath: "/Content/InfragisticsCSS/css",
        resources: "igSpreadsheet, igExcel.LoadSaveXlsx, igExcel.Functions",
        ready: function() {
                    //Initializing igSpreadsheet
            $("#spreadsheet").igSpreadsheet({
                height: "600",
                width: "100%",
                isFormulaBarVisible: false,
                allowAddWorksheet: false,
                allowDeleteWorksheet: false
            });
 
            $.ajax({
                url: '@Url.Action("GetReport3","Reports")',
              
                success: function(data) {
                    var responseArray = new Uint8Array(data);
                    var book = $.ig.excel.Workbook.load(data,
                        function(err, workbook) {
                            workbook = arguments[0];
                           
                        },
                        function() {
                            console.log("fail");
                        });
 
                    $("#spreadsheet").igSpreadsheet("option", "workbook", workbook);
                },
                error: function() {
                    createError('errorMessage', 'type');
                },
                complete: function() {
 
                }
            });
 
        }
    });
 
 
    $('#CompanyEntityId').selectize();
 
 
});

I either get one of two messages:

or 




****UPDATE****
It appears that the problem lies with Merged Cells You can Merge cells but when you add any value to them, Borders,fills,text, formulas the IgSpreadsheet will not read them.
