Thanks for contacting Syncfusion support.
We have analyzed your requirement and we suggest you to use the below way to achieve your requirement. You can bind actionBegin event and apply args.cancel as false to prevent the actions. Make AJAX request in actionBegin event and do your server side validation based on the AJAX success you may add the record programmatically by using addRecord method.
