React Slider - Overview

The Slider is a UI component that allows an end user to set a numeric value on a continuous range of possible values.

The following code adds a simple Slider to your page. The min and max properties limit the range of accepted values. The value sets the initial value for the UI component.

  • import React from 'react';
  • import 'devextreme/dist/css/dx.common.css';
  • import 'devextreme/dist/css/dx.light.css';
  •  
  • import { Slider } from 'devextreme-react/slider';
  •  
  • class App extends React.Component {
  • constructor(props) {
  • super(props);
  •  
  • this.state = {
  • value: 25
  • };
  •  
  • this.handleValueChange = this.handleValueChange.bind(this);
  • }
  •  
  • handleValueChange(e) {
  • const previousValue = e.previousValue;
  • const newValue = e.value;
  • // Event handling commands go here
  •  
  • this.setState({
  • value: newValue
  • });
  • }
  •  
  • render() {
  • return (
  • <Slider
  • min={0}
  • max={100}
  • value={this.state.value}
  • onValueChanged={this.handleValueChange}
  • />
  • );
  • }
  • }
  •  
  • export default App;

In addition, you can specify the step of Slider values using the step property.

  • import React from 'react';
  • import 'devextreme/dist/css/dx.common.css';
  • import 'devextreme/dist/css/dx.light.css';
  •  
  • import { Slider } from 'devextreme-react/slider';
  •  
  • class App extends React.Component {
  • constructor(props) {
  • super(props);
  •  
  • this.state = {
  • value: 25
  • };
  •  
  • this.handleValueChange = this.handleValueChange.bind(this);
  • }
  •  
  • handleValueChange(e) {
  • const previousValue = e.previousValue;
  • const newValue = e.value;
  • // Event handling commands go here
  •  
  • this.setState({
  • value: newValue
  • });
  • }
  •  
  • render() {
  • return (
  • <Slider
  • min={0}
  • max={100}
  • step={10}
  • value={this.state.value}
  • onValueChanged={this.handleValueChange}
  • />
  • );
  • }
  • }
  •  
  • export default App;
