Data Tables Row Checkbox Click Child Table Checkbox Always Checked

I have child tables attached to my datatable. Both tables and childtables have checked boxes attached. When the table's checkbox is checked, all the child table's checkboxes are checked. The problem is when the childtable is hidden the table check box is checked but the child table check box is not checked. This works if the child table is open. Re-hiding and opening it again becomes unchecked.
What I need is - when I check the check box(class="checkbox_check") of the table then the child table (name="Selectone" class="chk_isChecked")will be checked. If the child table is hide or open anyway.And input box (input type="number" value="0" class="txt_qty")value not be lost.

td.details-control {
background: url('') no-repeat center center;
cursor: pointer;

tr.shown td.details-control {
    background: url('') no-repeat center center;

<button onclick="addata()" class="btn btn-primary btn-sm">Add </button>

Order NO Total Value

await Html.RenderPartialAsync("_ValidationScriptsPartial");

<script type="text/javascript">
    function format(d) {
        var str = '';
        $.each(d.tbl_orderses, function (index, data) {
            str += '<tr>' +

    It doesn't look like you are keeping track of the checkbox state in the row data. I would look at using row().node(), in addition to getting row().data(), in your click event passing it to the format function:

                        else {
                            row.child(format(, row.node())).show();

    In the format function use the node parameter to get the sat of the checkbox and set the state of the child row checkboxes based on the fetched state.
