The Condition property is used to specify more complex validation criteria, such as whether a value lies within a given range. A required field condition can be enforced by setting the IsRequired property to true values are evaluated using the EmptyValueCriteria property if a value is determined by that definition to be null or empty, validation fails, causing the ValidationError event to fire. Validation criteria is specified using the properties of the object. Validation of embeddable editors is also supported this is accomplished by assigning a reference to an editor provider control such as an UltraTextEditor or UltraComboEditor to the EditorControl property of (for example) an UltraGridColumn or UltraTreeNodeColumn, then using the ValidationSettings instance extended to the editor provider control to customize the validation behavior for the grid/tree cell. This object encapsulates most of the validation functionality provided by the component since each control uses a separate instance, most aspects of the validation are customizable on a per-control basis. When an UltraValidator component is instantiated in design mode, a ValidationSettings instance is extended to every control on the form.

The UltraValidator component extends its functionality to all Windows Forms controls via the IExtenderProvider interface, which is utilized by Visual Studio to provide "extender properties". The designer support extended by the component is adequate for implementing these common solutions.

For typical validation scenarios such as ensuring that a number falls within a given range, or that a text field is non-empty, or conforms to the character pattern for a postal code, email address or telephone number, no code whatsoever needs to be written by the end developer. The UltraValidator component provides the ability to solve most common validation problems in a declarative manner.
