Show Slider from hidden state in React Range Slider component

28 Feb 20259 minutes to read

This section demonstrates how to render the Slider component in a hidden state and make it visible on button click. We can initialize the Slider in a hidden state by setting its display property to none.

In the sample, by clicking the button, we can make the Slider visible from its hidden state, and we must also call the refresh method of the Slider to render it properly based on its original dimensions.

import * as React from 'react';
import * as ReactDOM from "react-dom";
import { SliderComponent } from '@syncfusion/ej2-react-inputs';
import './index.css';
function App() {
    let sliderInstance;
    let min = new Date(2013, 6, 13, 11).getTime();
    let max = new Date(2013, 6, 13, 17).getTime();
    let value = new Date(2013, 6, 13, 13).getTime();
    let step = 3600000;
    // Slider ticks customization
    let ticks = { placement: "After", largeStep: 2 * 3600000 };
    let tooltip = { placement: "Before", isVisible: true };
    function renderingTicksHandler(args) {
        let totalMiliSeconds = Number(args.value);
        let custom = { hour: "2-digit", minute: "2-digit" };
        args.text = new Date(totalMiliSeconds).toLocaleTimeString("en-us", custom);
    }
    function tooltipChangeHandler(args) {
        let totalMiliSeconds = Number(args.text);
        let custom = { hour: "2-digit", minute: "2-digit" };
        args.text = new Date(totalMiliSeconds).toLocaleTimeString("en-us", custom);
    }
    function onClick() {
        const slider = document.getElementById("case");
        if (slider) {
            slider.style.display = "block";
            sliderInstance.refresh();
