You can define a method in your parent component, pass it to child component and call it from props every time child's state changes, keeping the state in child component.
look at this example
const EnhancedTable = ({ parentCallback }) => {
const [count, setCount] = useState(0);
return (
<button onClick={() => {
const newValue = count + 1;
setCount(newValue);
parentCallback(newValue);
}}>
Click me {count}
</button>
)
};
class PageComponent extends React.Component {
callback = (count) => {
// do something with value in parent component, like save to state
}
render() {
return (
<div className="App">
<EnhancedTable parentCallback={this.callback} />
<h2>count 0</h2>
(count should be updated from child)
</div>
)
}
}
