[Solved] Empty grid will send a ajax request automatically?

[FENG Zhichao]

I make a grid binding data on server side and make it can be refreshed by ajax request in client side.

if the server side data is empty, it seems the grid will send a ajax request automatically.

So the user can see a refresh on the page.

Is this right or i can do some config to avoid the automatic ajax refresh?

Thanks~~

Hello FENG Zhichao,

 Indeed the grid makes an ajax request initially when empty and ajax is enabled. You can modify the source of the grid in order to avoid that. To do so find this method and delete the highlighted section:

$.fn.tGrid = function(options) {
        options = $.extend({}, $.fn.tGrid.defaults, options);

        return this.each(function() {
            options = $.meta ? $.extend({}, options, $(this).data()) : options;

            if (!$(this).data('tGrid')) {
                var grid = new $t.grid(this, options);

                $(this).data('tGrid', grid);

                if (grid.$tbody.find('tr.t-no-data').length)
                    grid.ajaxRequest();
            }
        });
    }

i presently use the version 2011.1.315 of the grid. I have the very same problem as described by Feng. Is it possible for you to check if the data as been initlized server sided and if yes, do not fire an Ajax call if the grid is empty. I think its an easy one that would solve a few problems on my side.

thank you very much!

Hi Alexandre Jobin,

 We will not change this behavior because quite a lot of people rely on it. Use the workaround mentioned before.
