ValidationGroup
The ValidationGroup is a widget that allows you to validate several editors simultaneously.
You can use the DevExpress.validationEngine.validateGroup(group) method to validate a particular validation group by passing its instance as a parameter.
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.
