Welcome @cse.arunkumar

Thanks for sharing this solution but my requirement is different, here both dropdown’s data coming from database and
var wfdds_ddl_city = [’’];
var wfdds_ddl_country = [’’];
binding from db:
wfdds_ddl_city = wfdds_ddl_city .concat(response.data.City);
wfdds_ddl_country = wfdds_ddl_country .concat(response.data.Country);

declare out side handson table and city almost depend to country when user select country respective cities will reflect in city drodown.
in Cells: property I wrote this code:
if (col == wfdds_ddl_country ) {

                cellProperties.source = [];
                cellProperties.source = cityRenderer(row);
                
            }

after hotsettings I wrote this code:
function cityRenderer(row) {

        if (row != null) {
            var temp = $scope.DataObj[row][wfdds_ddl_country ];
           
            var modlist = [''];
            
            for (var i = 0; i < wfdds_ddl_country .length; i++) {
                if (wfdds_ddl_country [i].countryname == temp) {
                    modlist.push(wfdds_ddl_country [i].countryname );
                }
               
            }
        }
        
        return modlist;
        
    }

issue : when user select country, city drodown new data will come but old selected value not refresh.
Plz review and reslove my issue,

I can create you a demo that meets the project requirements but this is a commercial service. If you’re a PRO user with Extended Support I can schedule a review with one of our developers. I can share demos and example but I cannot prepare custom creations.

I’m not using this as commercial only for practice purpose, I heared abt Handson table that data will retrieve very smooth so plan to implement one of my module.
thanks

Thank you for the prompt reply. Relating to your message:

that does not change the offer.

If you want us to develop something especially for you, that has to be a commercial service (paid via Extended Support hours or additionally by bank wire transfer).
