Search panes gone after filtered and new draw()

Search panes gone after filtered and new draw()

I'm using the Buttons and SearchPanes extensions. I build a custom button who is filtering all rows with a value of 0. This works fine, but after this.draw(); my searchpanes are empty (No matching records found). I also tried with this.searchPanes.rebuildPanes(); after the draw, but nothing happens. Is there something I'm doing wrong or I'm missing?

My custom button is as follows:

className: 'showEmptyButton',
                    text: 'Hide empty',
                    action: function () {
                        if (this.text() === 'Show empty') {
                            this.text('Hide empty');
                        } else {
                                function(settings, data, dataIndex) {
                                    return parseInt(data[5]) > 0;
                            this.text('Show empty');

Thanks in advance. Let me know if you need further information.

    Built a test case for you.

    It doesn't seem to be behaving correctly. Will let the developers take a further look.

    Thanks for that test case, Kevin. Agreed, something looks wobbly there. I've raised it internally (DD-1604 for my reference) and we'll report back here when there's an update.

    Thanks a lot guys for the fast reply. Sorry that I didn't create a test case. I thought I did something wrong.

    Hi @Pete44 ,

    The key to this lies in your buttons functionality. Where you are adding your custom search function you are actually adding to every DataTable on the page. This in combination with the listeners that SearchPanes adds for the preDraw on the parent table causes the search function to run on the pane as well.

    To fix this you need to add a check to your search function to ensure that you are only running it on the desired table. Take a look at the below

    // Within the buttons action function the context is the parent table
    var tableNode = this.table(0).node();
        function (settings, data, dataIndex) {
            // Check that the search is running on the intended table
            if (settings.nTable !== tableNode) {
                return true;
            return parseInt(data[0]) > 0;

    I've updated the example to show this working for you.

    Hope this helps,

    mixing range filtering and search panes also causes the issue, and is fixed by the solution, thanks!
