jQuery ValidationGroup API

The ValidationGroup is a widget that allows you to validate several editors simultaneously.

import ValidationGroup from "devextreme/ui/validation_group"
Type:

Object

View Demo Read Guides

You can use the DevExpress.validationEngine.validateGroup(group) method to validate a particular validation group by passing its instance as a parameter.

JavaScript
DevExpress.validationEngine.validateGroup($("#sampleGroup").dxValidationGroup("instance"));

In addition, you can access a validation group's configuration using the DevExpress.validationEngine.getGroupConfig(group) method. The returned configuration exposes the validators included to the group, the validate() method to validate the editors that are associated with the validators and the validated event that occurs after the group is validated.

NOTE
Nested validation groups are not supported.
