set column value programmatically

[x1484]

Hello,

My grid is an inline editing grid, I started based on this example :
https://paramquery.com/demos/editing_custom

The 1st column is an article code (editable), the 2nd column being the article description (read-only)

1st column being an autocomplete field based on a PHP JSON mysql query, this column works as expected but when i get the result i would like to set the description cell to the right value.

How can i achieve this ? where is it better to set the column in the validations or in the autocomplete editor definition ?  I have put the code fragment below.

Thanks so much,
FX



var autoCompleteEditor = function (ui) {
            var $inp = ui.$cell.find("input");

            //initialize the editor
            $inp.autocomplete({
                appendTo: ui.$cell, //for grid in maximized state.
                source: function (query, result) {
                     $.ajax( {
                              url: '/getArticlesCodes.php',
                              cache: false,
                              async: false,
                              data:'art_code=' + query.term,           
                              dataType:"json",
                              type:"POST",
                              success: function (data) {

                                       result ( $.map( data,    function (item) {
                                                            return {    art_code: item.art_code,
                                                                     art_desc: item.art_desc,                                                                      
                                                                     label: item.art_code,
                                                                     value: item.art_code
                                                            };
                                                         }
                                                  )
                                             );
                                    }
                           } );
               },
                selectItem: { on: true }, //custom option
                highlightText: { on: true }, //custom option
                minLength: 0
            }).focus(function () {
                //open the autocomplete upon focus               
                $(this).autocomplete("search", "");
            });
        }
