[Solved] Modifying Grid bound to local data wont set dirty flag

[Kris]

Hi,

I have a grid which is bound to local JavaScript array. When i modify few records and try to get list of them, by checking "dirty" flag, i get nothing. Same when i try to retrieve deleted records; grid.dataSource._destroyed is empty.

var gridData = [
    { Id: 1, PaymentDate: '1/1/2015', Amount: 100 },
    { Id: 2, PaymentDate: '2/1/2015', Amount: 200 },
    { Id: 3, PaymentDate: '3/1/2015', Amount: 300 },
    { Id: 4, PaymentDate: '4/1/2015', Amount: 400 },
];

$(function() {
    $("#grid").kendoGrid({
        dataSource: {
            data: gridData,
            schema: {
                model: {
                    id: "Id",
                    fields: {
                        Id: { type: "number" },
                        PaymentDate: { type: "date" },
                        Amount: { type: "number" }
                    }
                },
            }
        },
        editable: {
            mode: "inline"
        },
        toolbar: ["create", "save", "cancel"],
        columns: [
            {
                field: "Id",
                title: "Id",
                width: "150px"
            },
            {
                field: "PaymentDate",
                title: "Payment Date",
                format: "{0:" + dateFormat + "}",
                width: "150px"
            },
            {
                field: "Amount",
                title: "Amount",
                format: "{0:c}",
                width: "150px"
            },
            {
                command: ["edit", "destroy"]
            }
        ]
    });

    grid = $("#grid").data("kendoGrid");
})

function show() {
    var data = grid.dataSource.data();
    var destroyed = grid.dataSource._destroyed;

    for (i = 0; i < data.length; i++) {
        if (data[i].dirty) {
            console.log(data[i].Id);
        }
    }

    for (i = 0; i < destroyed.length; i++) {
        console.log(destroyed[i].Id);
    }
}

Please suggest how i may do this.

Hello,

This happens because inline editing automatically syncs the changes which in the case of local transport are automatically accepted hence no dirty flag. You could either use in cell edit mode or create a custom transport like this: http://dojo.telerik.com/@korchev/URaju
