Uncaught TypeError: Cannot read property 'insert' of undefined

[anna]

Try to use the Drag and Drop to reorder the rows. 
I'm stuck in an error that I'm not figuring out.

The error: Uncaught TypeError: Cannot read property 'insert' of undefined

The line: grid.datasource.insert(newIndex, dataItem );

I'm sure the datasource has data, since the "console.log(dataItem)" returns the object model

var Material = new kendo.data.Model.define({
    id: "NR_position",
    fields: {
        NR_position: { type: "number" },
        CD_Material: { type: "number" },
        NM_Material: { type: "string" }
    }
});

var Controller = {
    dataSource: {        
        ListMat: new kendo.data.DataSource({
            transport: { read: { url: matList, type: "POST" } },
            model: Material,             
            dataType: "json",
            url: "data/person.json"
        })
    },
    init: function () {
        var grid = $("#grdMatOrder").kendoGrid({
            dataSource: Controller.dataSource.ListMat,
            columns: [
                { field: "NR_position", title: "Order" },
                { field: "CD_Material", title: "Code" },
                { field: "NM_Material", title: "Name" }
            ]
        }).data("kendoGrid");

        grid.table.kendoSortable({
            filter: ">tbody >tr",
            hint: function (element) {
                var table = $('<tr colspan=4" class="placeholder></ tr>'), hint;

                table.append(element.clone());
                table.css("opacity", 0.7)                

                return table;
            },

            change: function (e) {
                var skip = grid.dataSource.skip(),
                    oldIndex = e.oldIndex + skip,
                    newIndex = e.newIndex + skip,
                    data = grid.dataSource.data(),
                    dataItem = grid.dataSource.getByUid(e.item.data("uid"));

                console.log(dataItem)

                grid.dataSource.remove(dataItem);
                grid.datasource.insert(newIndex, dataItem );
            }
        });
    }
};


$(document).ready(function () {
    Controller.init();
});

Hi Anna,

I am not able to replicate this behavior and furthermore, the Sortable is working just fine in the following official demo:

https://demos.telerik.com/kendo-ui/sortable/integration-grid

Could you please modify it (by clicking on the Edit in Kendo UI Dojo tab) to showcase the problem s oI can advise further?

Regards,

Nikolay
