$(function() {
    const progressBar = $("#progressBarContainer").dxProgressBar({
        // ...
    }).dxProgressBar("instance");

    function setInvalidStatus(message) {
        progressBar.option({
            validationStatus: "invalid",
            validationErrors: [{ message: message }]
        });
    }
});
Angular

    validationStatus: string = "valid";
    validationErrors: any;
    // ...
    setInvalidStatus(message) {
        this.validationStatus = "invalid";
        this.validationErrors = [{ message: message }];
    }

            }
        },
        methods: {
            setInvalidStatus(message) {
                this.validationStatus = "invalid";

import React, { useState } from 'react';

    const setInvalidStatus = message => {
        setValidationStatus("invalid");
        setValidationErrors([{ message: message }]);
