    Hello, I am struggling with a weird error while canceling a newly inserted row in a grid. Please help.

    Below is a simplifed version of my code (

    var myGrid = $("#my-table-grid").kendoGrid({
      toolbar: [ {
                        name: "create",
                        text: "Create"
                    } ],
      editable: { mode: "inline", confirmation: false },
      columns: [
        { field: "name" },
        { field: "age" },
        { command: [{ name: "edit"}] }
      dataSource: {
        //data: [],
        data: {"a": []},   
        schema: {
          data: "a",
          model: { id: "id",
              fields: {
                 id: {type: "number"},
                 name: {type : "string"},
                 age: {type: "number"},


    Steps to reproduce:

    1. Click the "Create" button to insert a new row.

    2. Fill in any data and click "Update" to save the row.

    3. Click the "Create" button to insert a second row.

    4. Click "Cancel" button right away without filling in any data in the second row.


    The second row will NOT be canceled. Error message "Uncaught TypeError: Cannot read property 'uid' of undefined" is shown in the console.


    This issue will not occur for the first row added (You can cancel the first row). Also, if I do not specify the data field in the dataSource section (, it works fine too. In my real case, the data comes from a API call with structured JSON data so this is not an option for me.


    I wonder if I misconfigured something or this is a bug. Please help. Thanks a lot in advance.

    Hi Rak,

    Thank you very much for the provided runnable sample.

    To enable editing of the Kendo UI Grid, the Data Source should be configured for CRUD operations:

    Once, this is done, everything works as expected:

    For more demos, you may check out the official demos site, e.g. remote data source CRUD operation with inline editing is available at:

    I hope this helps.
