Hi jaiarih, you can do this still using beforeUpdate event:
new Grid({
....
store : {
listeners : {
beforeUpdate({record, changes}) {
console.log("Previous value for field 'yourFieldName': " + record.yourFieldName);
console.log("New value for field 'yourFieldName': " + changes.yourFieldName);
}
}
},
....
}
or you can do the samething with update event
grid.store.on('update', (event) => {
console.log(event);
});
