Server side paging in DHTMLX Tree Grid using PHP connector

Hi i am trying to use
$conn->dynamic_loading();
and
$conn->render_sql($sql,$id,$text,$extra,$relation_id);
to implement server side paging in Tree Grid.
As defined ( $relation_id - used for building hierarchy in case of Tree and TreeGrid.), I have set all the parameters and the resulting XML does not have parent child XML structure.
What am i missing here? Is there a detailed working example which could guide me the usage of render_sql for TreeGrid?

Unfortunately the problem cannot be reproduced locally.
Please, try to download the latest connector build from here:

You can find a working example in the “connector/samples/treegrid/02_dynamic_loading.html”

I did read paging is not supported for DHTMLX treegrid as mentioned here

  • treegrid - dynamic branch loading mode

Is server side paging supported now?

paging mode is enabling on the client-side and have no relation to the server-side. You can use it in your dhtmlxTree if you need to.
