A function passed to this property should take on a numeric value and return a formatted value. For instance, you can add a "%" sign after a value. In this case, the function passed to the statusFormat property should look like the following.

JavaScript

function(ratio, value) {
    return ratio * 100 + "% (" + value + ")";
}

The function may also return a string containing a Globalize format pattern.

Selector: validation-message-position

Type:

Position

Default Value: 'bottom'

The following example positions a validation message at the component's right:

jQuery

index.js

$(function() {
    $("#progressBarContainer").dxProgressBar({

        validationMessagePosition: 'right'
    }).dxValidator({
        validationRules: [{

    <dx-validator>
        <dxi-validation-rule
            type="required"
            message="Required"
        >
        </dxi-validation-rule>
    </dx-validator>
</dx-progress-bar>

Vue

App.vue

<template>
    <DxProgressBar ...
        validation-message-position="right"

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

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

Angular
