Property Value

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

Remarks

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.

C#

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

VB.NET

Imports System.Collections.ObjectModel
' ...
Public Overrides ReadOnly Property UsedProperties() As ReadOnlyCollection(Of String)
    Get
        Return New ReadOnlyCollection(Of String)(New List(Of String)() From {"Amount"})
    End Get
End Property

Important

Always define UsedProperties for warning and info rules.
