An object that specifies what and when to validate, and how to apply the validation result.

Type: Object

This option should be specified when you cannot associate the dxValidator widget with an editor, because, for instance, you use custom editors or a validated value is a concatenation of several DevExtreme editor values. For details, refer to the Validate Custom Editors topic.
