Lazy load for big dataset

Hi, I want to load some part of my data in datatable. And then with the help of pager to load next part of data and so on. I tried samples on documentation but I did not achieve to my aim. I add datafetch and loadahead to javascript code, but there is no effect. How can I do it?

First of all, please check the backend of the related sample locally (in the Webix package this sample available at samples\\15_datatable\\19_paging\\03_db_data_dyn.html).

Also, you can try to use loadNext API to load data manually.

Thanks for your reply. I checked the backend of shown sample (03_db_data_dyn.html) but there is no effect. I tried the same thing to my code but it did not work for me. What else can I do?

Could you please provide a sample of your implementation?

Of course I can. This is my table:

           var table = {
                id: 'request_dtable',
                uri: 'request/all',
                url: 'request/all?filter=2&ports=2,25',
                view: 'datatable',
                css: 'request_dtable',
                scrollX: true,
                headerRowHeight: 90,
                rowHeight: 30,
                navigation: true,
                select: 'row',
                datafetch:40,
		loadahead:15,
                //multiselect: true,
                pager: 'request_table_pager',
                columns: [
                       // columns goes here
                ]
            };

And it is my pager:

            var pager = {
                view: "pager",
                id: 'request_table_pager',
                template: '{common.first()} {common.prev()} {common.pages()}    
                                {common.next()} {common.last()}',
                size: 50,
                group: 3,
                height: 30
            };

Hi @Listopad. What is the solution for this problem? Can you help me?

Config itself is right (except there’s no uri property).

Please double-check your server-side script. The required pattern of the request and the server response are described here.

Thank you @Listopad, you just saved my day. I appreciate your help.
