React CheckBox - Overview
The CheckBox is a small box, which when selected by the end user, shows that a particular feature has been enabled or a specific property has been chosen.
The following code adds the CheckBox to your page.
App.js
- import React from 'react';
- import 'devextreme/dist/css/dx.common.css';
- import 'devextreme/dist/css/dx.light.css';
- import CheckBox from 'devextreme-react/check-box';
- class App extends React.Component {
- constructor(props) {
- super(props);
- this.state = {
- checkBoxValue: undefined
- };
- this.handleValueChange = this.handleValueChange.bind(this);
- }
- handleValueChange(e) {
- this.setState({
- checkBoxValue: e.value
- });
- }
- render() {
- return (
- <CheckBox
- text="Check me"
- value={this.state.checkBoxValue}
- onValueChanged={this.handleValueChange}
- />
- );
- }
- }
- export default App;
The CheckBox UI component can have the following states: checked (the value property is true), unchecked (value is false), undetermined (value is undefined).
