When you assign "invalid" to validationStatus, you can also use the validationErrors array to set an error message as shown below:

jQuery
index.js
$(function() {
    const rangeSlider = $("#rangeSliderContainer").dxRangeSlider({
        // ...
    }).dxRangeSlider("instance");

    function setInvalidStatus(message) {
        rangeSlider.option({
            validationStatus: "invalid",
            validationErrors: [{ message: message }]
        });
    }
});
Angular
app.component.html
app.component.ts
<dx-range-slider
    [validationStatus]="validationStatus"
    [validationErrors]="validationErrors">
</dx-range-slider>
// ...
export class AppComponent {
    validationStatus: string = "valid";
    validationErrors: any;
    // ...
    setInvalidStatus(message) {
        this.validationStatus = "invalid";
        this.validationErrors = [{ message: message }];
    }
}
Vue
App.vue
<template>
    <DxRangeSlider ...
        :validation-status="validationStatus"
        :validation-errors="validationErrors"
    />
</template>

<script>
    // ...
    export default {
        // ...
        data() {
            return {
                validationStatus: "valid",
                validationErrors: []
            }
        },
        methods: {
            setInvalidStatus(message) {
                this.validationStatus = "invalid";
                this.validationErrors = [{ message: message }];
            }
        }
    }
</script>
React
App.js
import React, { useState } from 'react';
// ...

function App() {
    const [validationStatus, setValidationStatus] = useState("valid");
    const [validationErrors, setValidationErrors] = useState([]);

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

    return (
        <RangeSlider
            validationStatus={validationStatus}
            validationErrors={validationErrors}
        />
    );

Type:

String

Default Value: 'onHandleMove'
Accepted Values: 'onHandleMove' | 'onHandleRelease'

If you want to change the component's value after a user releases the component's handle, set this property to onHandleRelease. The moment when the onValueChanged function is called depends on this property:

jQuery
index.js
$(function() {
    $("#rangeSliderContainer").dxRangeSlider({
        // ...
        valueChangeMode: 'onHandleRelease',
        onValueChanged: function (e) {
            const previousValue = e.previousValue;
            const newValue = e.value;
