Hi Rahul,
Greetings from Syncfusion Support.
You can get the save button click event using popupClose event or actionBegin event. Please refer to the following UG and sample.
actionBegin: function(args) {
if (
args.requestType == 'eventCreate' ||
args.requestType == 'eventChange'
) {
console.log(args.data);
}
},
popupClose: function(args) {
if (args.type == 'Editor' && args.data != null) {
console.log(args.data);
}
}
Please try the above solution and let us know if you need any further assistance.
Regards,
Nevitha
