Is it possible to disable/enable column sorting programmatically?

donnie

Hi,

I made a plugin which allows to sort columns of a datatables, by dragging the border of a th element.
I took most of the code from this discussion: http://datatables.net/forums/discussion/2474/column-resizing/p3

I finally have something that works well, except that when I release the mouse button after the drag and drop, a sorting happens on the columns.

I would like to disable the sorting temporarily, so that there is no column sorting after I finish resizing a column.

I tried to find a function in the API, I tried to look in this forum, without success.

Is there a way to achieve it?

Thanks a lot.

You might need to call event.stopProagation() to stop the click event bubbling up to DataTables. If you post an example, that might let us take a look and see what is happening.

I tried but it did not work.

Like in ColReorder plugin, my plugin binds a "mousedown" and a "mouseup" event on the <th> element.
When I click on a th element to sort the appropriate column, it seems to me that the sorting happens in the mouseup callback. So I tried to do e.stopPropagation() from my _fnMouseUp() function, without success. Then I also tried to do it from the _fnMouseDown() function, but no success either.

I cannot post the full example, but here is the idea:

this._fnMouseListener = function(i, nTh) {
    $(nTh).on('mousedown.ColResize', function(e) {
        e.preventDefault();
        that._fnMouseDown.call(that, e, nTh);
    });
};

this._fnMouseDown = function(e, nTh) {
    // I tried here, without success
    e.stopPropagation();

    $(document).on('mousemove.ColResize', function (e) {
        that._fnMouseMove.call(that, e);
    }).on('mouseup.ColResize', function (e) {
        setTimeout(function () {
            that._fnMouseUp.call(that, e);
        }, 10);
    });
};

this._fnMouseUp = function(e) {
    // I also tried here, without success
    e.stopPropagation();
};

Wherever I put this e.stopPropagation(), the column sorting is still performed.

I don't understand in the ColReorder plugin, why the sorting is not performed when clicking on a column to reorder it?!

I would need to do the same in my plugin, but cannot figure out how it's done in the ColReorder plugin.

It might be this - although i'd need to experiment to be sure (I has been a while since I've worked on that bit of code).

Hello allan,

I haven't had time to try it yet, but I will soon and I will give a feedback here.

Thank you!
