Kendo UI Grid for MVC export to Excel does nothing

Question

I am using Kendo grid for MVC 4.0. I have the latest DLL 2015.1.318.440. I am including jszip.js. I copied and pasted the code from the example:

          .ToolBar(tools => tools.Excel())
          .Excel(excel => excel.FileName("Enrollments.xlsx"))

It does nothing. The button changes color and that's it. I don't get any errors when I try it. It just doesn't do anything. I am not using a proxy server. I am running this in Chrome latest version.

The grid

@(Html.Kendo().Grid<Trawick.Agents.Models.EnrollmentPolicy>()
.Name("grid")
    .ToolBar(tools => tools.Excel())              
    .Excel(excel => excel
   .FileName("Enrollments.xlsx")
       .Filterable(true)
       .ProxyURL(Url.Action("Excel_Export_Save", "Enrollments"))
     )              
     .Columns(columns =>
      {
       columns.Bound(p => p.enrollment_date)
          })
     .Pageable()
     .Groupable()
     .Sortable()
     .DataSource(dataSource => dataSource
     .Ajax()
     .PageSize(20)
     .Read(read => read.Action("Enrollments_Read", "Enrollments")))
)

The controller

    [HttpPost]
    public ActionResult Excel_Export_Save(string contentType, string base64, string fileName)
    {
        var fileContents = Convert.FromBase64String(base64);

        return File(fileContents, contentType, fileName);
    }
    public ActionResult Enrollments_Read([DataSourceRequest]DataSourceRequest request, int? id)
    {
        string sql = "SELECT * FROM EnrollmentPolicy ";
        sql += SearchParams.SetSearch(this);
        return Json(GetEnrollments(sql).ToDataSourceResult(request));
    }

Bundle file including jszip

bundles.Add(new ScriptBundle("~/js/kendo")
     .Include("~/Scripts/jszip.js")
     .Include("~/Scripts/kendo.all.min.js")
     .Include("~/Scripts/kendo.aspnetmvc.min.js"));

Answer 1

        bundles.Add(new ScriptBundle("~/js/kendo")
            .Include("~/Scripts/kendo.all.min.js")
            .Include("~/Scripts/kendo.aspnetmvc.min.js")
            .Include("~/Scripts/jszip.js"));

This was the issue.jszip has to be included AFTER the kendo scripts (this is the opposite of what the documentation says).

Answer 2

My issue was related to volume - smaller number of records work, large batches do not. My current workaround is to set AllPages(false) and then it will just export a filtered list. See http://www.telerik.com/forums/excel-export-not-working-with-more-than-a-thousand-records
