Type Description

A ReadOnlyCollection<String> object representing a list of the property names that must be highlighted as invalid when the Validation Rule is broken.


The Validation Module can highlight Property Editors in a View when a Validation Rule is broken. When implementing the IRule interface, to highlight properties containing invalid values, pass the required property names via the UsedProperties property.

using System.Collections.ObjectModel;
// ...
public override ReadOnlyCollection<string> UsedProperties {
    get {
        return new ReadOnlyCollection<string>(new List<string>() { "Amount" });


Always define UsedProperties for warning and info rules.
