    I am having this issue with scroller version 1.5.1 it simply does not move. Code:

                    var table = $('#table').DataTable({
                        "paging": true,
                        "pageLength": 15,
                        "order": [],
                        "scrollX": true,
                        "scrollY": true,
                        scroller: true,
                    });
    

    data is on DOM

    I am attempting:

    table.row(8).scrollTo();
    

    but nothing

    Hi @diegoponciano ,

    That's right, that's the problem in the OP. This is now fixed, but not yet released, so you'll need to grab one of the nightly builds to get the fix. Apologies for the inconvenience,

    Cheers,

    Hi team,

    I'm also having an issue with ScrollTo, as with the posters above it just seems to sit there at the top of the table. I just downloaded the latest version of datatables, so I'm on version 1.10.18.

    My function to load the table, initialize it, and scrollTo are all in the same function and look like below. I've even tried moving the scrollTo outside of the function, wrapping the getData() function inside a $.when.done, and then calling scrollTo, and it still didn't help.

    function getData() {
        var param = { pageID: pageID }
    
        return $.ajax({
            type: "POST",
            contentType: "application/json; charset=UTF-8",
            url: "WebServices/attData.asmx/getWeeklyMonitoringByArea",
            data: JSON.stringify(param),
            dataType: "json",
            success: function (response) {
                var wm = response.d;
                var firstActive = true;
                var rowIdx = 0;
    
                if ($.fn.DataTable.isDataTable('#tblWM')) {
                    $('#tblWM').DataTable().clear().destroy();
                }
    
                var dt = $('#tblWM').DataTable({
                    paging: false,
                    info: false,
                    sort: false,
                    scrollX: true,
                    scrollY: '60vh',
                    scrollCollapse: true,
                    dom: 'Brt',
                    buttons: [
                        'copyHtml5', 'excelHtml5', 'pdfHtml5', 'print'
                    ],
                    data: wm,
                    columns: [
                        {

    Hi @puffster ,

    There was an outstanding issue for this, which was fixed this afternoon and will be available in the nightly build from tomorrow. You can find the nightly releases here.

    Please could you try this again next week with that build and let us know if it addresses your issue.

    Cheers,

    Colin

    Apologies for taking so long to get back on this...I'm using the nightly releases but it's still not working. It's entirely possible that I'm doing something incorrect.

    Here's my calls to the nightly release:

        <link rel="stylesheet" href="https://nightly.datatables.net/css/jquery.dataTables.min.css">
        <link rel="stylesheet" href="https://nightly.datatables.net/buttons/css/buttons.dataTables.min.css" />

        <link rel="stylesheet" href="https://nightly.datatables.net/scroller/css/scroller.dataTables.min.css" />
    
        <script src="https://nightly.datatables.net/js/jquery.dataTables.min.js"></script>
        <script src="https://nightly.datatables.net/buttons/js/dataTables.buttons.min.js"></script>
        <script src="https://nightly.datatables.net/buttons/js/buttons.flash.min.js"></script>
        <script src="https://nightly.datatables.net/buttons/js/buttons.html5.min.js"></script>

        <script src="https://nightly.datatables.net/scroller/js/dataTables.scroller.min.js"></script>
    

    And my javascript...the rowIndex & datatable both are showing correctly in the console.log:

    var pageID = "91";
    var rowIdx = 0;
    var dt;
    
    $(document).ready(function () {
        //getUserSelectedLocation();
        $.when(getData()).done(function () {
            console.log(dt);
            dt.row(rowIdx).scrollTo();
        })
    });
    
    function getData() {
        var param = { pageID: pageID }
    
        return $.ajax({
            type: "POST",
            contentType: "application/json; charset=UTF-8",

                if ($.fn.DataTable.isDataTable('#tblWM')) {
                    $('#tblWM').DataTable().clear().destroy();
                }
    
                var lastWeek = wm[0].endDate;
                var colorClass = '';

                        if (data.active == 1) {
                            $(row).find('td').addClass('activeRow');
                        }
    
                        if ((data.currentWeek == 1) && (firstActive)) {
                            rowIdx = dataIndex;

                });
            }
        });
    }
    

    I hope it's something I'm not doing right!!

    Hi @puffster ,

    There's a lot of code there. It's working in this example here - could you modify that example to demonstrate your problem, or could you link to your page.

    Cheers,

    Colin

    Hi @colin

    I am also trying to achieve same thing as @puffster. The example you have posted is not working if paging is set to false and do I need to set scroller="true" to make scroll to row work?

    The example you have posted is not working if paging is set to false

    The Scroller docs indicate paging must be enabled with this comment:

    making use of the pagination abilities of DataTables and moving the table around in the scrolling container

    do I need to set scroller="true" to make scroll to row work?

    Yes, row().scrollTo() is a Scroller extension API. It looks like that is the problem with @puffster 's code. The Scroller extension was loaded but doesn't look like it was enabled.

  • velagacvelagac Posts: 3Questions: 0Answers: 0

    @kthorngren Is there any way to scroll to specific row without setting scroller=true?

  • colincolin Posts: 3,646Questions: 0Answers: 643

    Hi @velagac ,

    No, row().scrollTo() needs scroller. This SO thread looks there's an alternative solution for you,

    Cheers,

    Colin

  • velagacvelagac Posts: 3Questions: 0Answers: 0

    @colin, thanks. Just used similar solution to fix my problem.
