"Uncaught ReferenceError: sum is not defined" when grouping grid

[Uwe]

Dear support

Currently working on a MVC 4 project, I get an error when using a group footer template for a field in a grid:

groupFooterTemplate: "#= sum #"

The above line results in an error

"Uncaught ReferenceError: sum is not defined"

when grouping the grid.

I've included a stand-alone proof-of-concept project. The file "Index.cshtml" contains some comments in line 91 and 99 to highlight the row that procudes the error.

My question is:

Could you please kindly take a look at my attached project and tell me how I should change the code so that the sum is correctly printed in the footer of a cell?

Thanks
Uwe

Finally, I solved it.

What I did was to forget to dynamically set the aggregates for the group.

Old code:

ds.group({ field: column });

New code:

ds.group({ field: column,

    aggregates:[

        { field: "Three", aggregate: "sum" },

        { field: "Four", aggregate: "sum" }] });

So I'm just happy now :-)

I had a similar problem but it was because I put the aggregate code into the grid instead of into the datasource.

// following is part of the datasource
aggregate:[
        { field: "Three", aggregate: "sum" },
        { field: "Four", aggregate: "sum" }] });

In my case does not coincide with the model aggregate field.
I had this

columns.Bound(model => model.Monto1).Filterable(false).Format("{0:n0}").HtmlAttributes(new { align = "right" }).ClientFooterTemplate("<div style='float: right'>#= kendo.toString(sum, 'n0') #</div>").Title("mes1");

...
  .DataSource(dataSource => dataSource
    .Aggregates(aggregates =>
    {
        aggregates.Add(model => model.Monto2).Sum();
    })

 

and the correct is:

aggregates.Add(model => model.Monto1).Sum();
