Default Value: 'valid'

The following table illustrates the validation status indicators:

validationStatus Indicator
"pending" DevExtreme editor validation status: pending
"valid" DevExtreme editor validation status: valid
"invalid" DevExtreme editor validation status: invalid

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

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