    I'm having trouble getting the export to excel working, it throws  Cannot read property 'length' of undefined in jquery


    Here is MVC Grid Declaration:

          .Columns(columns =>
              columns.Bound(m => m.StudentCode);
              columns.Bound(m => m.date).Title("Date");
              columns.Bound(m => m.amount).ClientTemplate("#=kendo.toString(data.amount,'c')#").Title("Amount");
          .ToolBar(toolbar =>
          .Excel(e =>
          .DataSource(dataSource => dataSource
              .Read(read => read.Action("StudentPayments_Read", "PaymentsGrid").Data("getCompletedData"))


    In case you need getCompletedData: 

    function getCompletedData() {
            return {"id" : @ViewBag.LocationId, "date":sel};


    sel is just a string containing date information like "01 2017"


    public class TransactionViewModel
            public string StudentCode;
            public decimal amount;
            public string date;


    Everything seems pretty simple, I can't see what I'm missing. The controller was scaffolded so was the grid. I had to add the filename for the excel export, and I added the date filter.

    I tried adding a proxyurl but it didn't change the result so I took it out, assuming its not needed.

    Any help is appreciated,
    Thank you

    I have modified our Export to Excel demo to be similar to your scenario and it works as expected.

    Can you please send us an isolated runnable project, where the described problem can be observed, so we can inspect it further, and try to determine what might be causing it? A dojo example will be also helpful.

    Thank you in advance.

    When I tried to create a new project with a new installation of kendo it worked. I thought I was just missing something but I guess there was something up with my kendo installation. Reinstalling it worked.

    Thank you very much for your time,
