    Hi! I have a table with child rows and I use ColReorder and it is set to true in the def. I can move columns - that is fine, but right next to pretty much each column except column 0 there are child rows columns. How can I make ColReorder move 2 columns at once, so that each associated child row column moves together with the column which is being moved? Somehow this has to be defined but not sure how. Anyone ever tried this? Any help appreciated!!

    I wanted to know if it is possible to navigate the list only up and down and not allow horizontal navigation between cells and allow only the navigation with the keys with only between the rows.

    I have a datatables in a partial view which pop up in a view with another datatable.

    but the datatable fonts in the model dialog comes blank. so i added custome css but it affects the table in the main view too. and even with two different names ,model dialogue's datatable refreshes after loading and i think cos its redrawen by the main page datatables code. any idea on how to fix would be very much appreciated.

    Thank you

    When I open the page on iPhone se simulator(width:320px),
    the fixed header looks wilder than the original one.

    I've check it and try add a line in js file:

    _modeChange: function ( mode, item, forceChange )
            var dt = this.s.dt;
            var itemDom = this.dom[ item ];
            var position = this.s.position;
            console.log(position.width+'|'+$('.dataTables_wrapper').width()) //I added this

    And I got:


    On real phone, it's 410|400.
    Whatever, the fixedHeader got a bigger size.

    Had I do something wrong?

    Hi all!
    I know the code to sum it up and I tried to edit it for my purpose. I want to multiply the value of column 1 and column 6 and sum up all results.

    I tried it with this code:
    "footerCallback": function ( row, data, start, end, display ) {
    var api = this.api(), data;
    // Remove the formatting to get integer data for summation
    var intVal = function ( i ) {
    var quantity = data.quantity;
    var finalproduct = i * quantity;
    return finalproduct;

                    // Total over all pages
                   var total = api
                        .column( 6 )
                        .reduce( function (a, b) {
                            return intVal(a) + intVal(b);
                        }, 0 );
                    // Total over this page
                   var pageTotal = api
                        .column( 6, { page: 'current'} )
                        .reduce( function (a, b) {
                            return intVal(a) + intVal(b);
                        }, 0 );
                    // Update footer
                    $( api.column( 6 ).footer() ).html(
                        '$'+pageTotal +' ( $'+ total +' total)'

    but no success :( ... thank you very much for any help in advance!

    I have a table with 3000 rows. I need to preselect some of the rows. Rowcreate only selects that the rows have been rendered. Is there a way to select before they are rendered?

    Also can the data be filtered to show only the selected records?

    In your section on sorting on live DOM

    You have an sorting mechanism for "dom-text-numeric" which should sort the column based on the numeric values of the textbox.

    The example however appears to sort on the string rather than the value and fortunately the data in the example table only has 2 digit values. When you also have single digit values in the textbox the sorting mechanism classes "4" to be 'greater' than "22" as it seems to sort on text rather than the actual value?

    If you add a 2 character manipulation (i.e. if (d<10) then return "0" + d;) to the sorting mechanism before the return, then the sorting mechanism works as intended.

    Is there a method to implement that will sort on the actual value, rather than the string ?

    I am trying to reload my table on the click of a button using table.ajax.reload().
    I'm getting an invalid JSON error and upon going through troubleshooting with datatables/tn1, I can see that it is returning html/text instead of JSON.
    How do I parse the data on reload?
    I've tried various ways of combining table.ajax.reload() with JSON.parse(), but none have worked.

    Hi, We are using DataTables to edit some data on client side, but we have issues if we use reordering option or if we delete rows.
    In general we need functionality which is in this example, but on Client side

    Do you have any hints how to update DataTables after we do some manipulation like deleting elements or reordering.
    It would be perfect to get same example working on Client side data.

    I'm getting the data in response but can't add it the datatable row. Can anyone please help me out with this?

    This is what I'm trying to do:

    export default (id) => {
      if (!$.fn.dataTable) return;
        destroy: true,
        pageLength: 8,
        responsive: true,
        ordering: false,
        searching: false,
        info: true,
        lengthChange: false,
        stripeClasses: [],
        processing: true,
        serverSide: true,
        ajax: {
          url  : `${Config.baseUrl}/homepark/list?page_no=1&settingType=dashboard&isActive=1&categoryId=active-listings`,
          type : 'GET',
          "beforeSend" : function(xhr) {
          "dataSrc": function ( json ) {
            const data = json.response.users
            console.log('@@@', data);
            // data = data.row\````

    This is what I'm getting as a result from backend in json.response.users:

    (9) [{…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}]
    0: {name: "testt", data: "0"}

    4: {name: "testt11", data: "4"}
    5: {name: "testt11", data: "5"}
    6: {name: "testt11", data: "6"}

    Per the title, the CSS for the Choose File and Clear File buttons are wrong. For example:

    <button class="btn btn-default">Choose JPG...</button>

    btn-default is not a valid Bootstrap 4 style.

    I made it pretty with:

    editor.on('open', function () {
        $('.upload button').addClass('btn-outline-primary btn-sm');
        $('.clearValue button').addClass('btn-outline-danger btn-sm');

    Trying to get select2 createTag to work per I get error at dataTables.editor.js line 5275 because canReturnSubmit not defined for the field.

    found, but not sure the correct setting. In any case the select2 fieldtype plugin should be updated if canReturnSubmit is required

    Else dataTables.editor.js should verify function exists before calling it

    See, and enter some new option into the select search box for col0

    Hi. I'm facing a strange issue on my dataTable. I've implemented a rowReorder function (including event) and this is working perfectly fine except one scenario. When I click a column to enable the sorting I want to disable to rowReorder if the column is not the Order column, and for this I have an event set for 'th' and this is also working perfeclty fine. So for example if I click on the column Name to sort the table by this column then the rowReorder (drag and drop) is disabled, and if i click the Order column to sort the table by this column then the rowReorder is enabled and its working fine. My issue is when I click the Name column header to sort the table by Name to disable the rowReorder function and I refresh the page, even if Im checking for what column has sorting enabled my rowReorder is always enabled event thought I'm calling the rowReorder.disable(). Below is code for my dataTable. Please help

    $(document).ready(function () {
        var dataTable = $("table.reorder-table").DataTable({
                language: GetLanguage(),
                lengthMenu: [[10, 25, 50, 100, 250, 500, 1000], [10, 25, 50, 100, 250, 500, 1000]],
                serverSide: true,
                processing: true,
                stateSave: true,
                ajax: {
                    url: GetDataRequestUrl(),
                    type: "POST",
                    datatype: "json",
                    error: function (xhr, errorType, exception) {
                        $("table.reorder-table tbody").html("");
                                '<tbody><tr class="odd"><td colspan="100%" class="dataTables_empty" valign="top">No data</td></tr></tbody>');
                columns: GetColumnDefinitions(),
                rowReorder: {
                    selector: "td:not(:last-child)",
                    dataSrc: "Order",
                    update: false
                function () {
                    // if the column header clicked is Order then enable the rowReorder
                    if (dataTable.column(this).index() === 0) {
                        dataTable.rowReorder.enable(); // <-- working like it should
                    else {
                        dataTable.rowReorder.disable(); // <-- working like it should
            //  below is called after page is reloded (refreshed) but its not disabling the rowReorder function 
            var order = dataTable.order();
            var colIndex = order[0][0]; // <-- get the index of the column where the sorting is applied
            if (colIndex === 0) { // <-- if the column is Order column 
            } else {
                dataTable.rowReorder.disable(); // <-- this is called but not working

    We are already using DataTables in our mvc 5 web application and are considering buying Editor to support local, inline editing. We appreciate the existence of the .net libraries for server side code but are a bit confused about how the whole thing work and if it is going to fit our needs.

    More specifically, there is no database in our project. The data are provided by web services, instead. Right now, we are using a simple ajax Datatables call to fetch and show the data. Everything (the columns, the rendering etc) is defined client-side in the DataTables initialization.

    Is the Editor .net library any good to us? or is it specifically for database connection only?

    I would like to set Datepicker options for a date field, are all the jQueryUI Datepicker options available? I am loading the jQueryUI Datepicker, so I assume that is the datepicker the Editor is using. When I set the "showOtherMonths" to true it doesn't seem to have any effect when the calendar shows.
