Binding::NotifyOnValidationError Property
Gets or sets a value that indicates whether to raise the Error attached event on the bound object.
Assembly: PresentationFramework (in PresentationFramework.dll)
If the binding has ValidationRules associated with it, the binding engine checks each rule each time it transfers the target property value to the source property. If a rule invalidates a value, the binding engine creates a ValidationError object and adds it to the Validation.Errors collection of the bound object. When the Validation::Errors property is not empty, the Validation::HasError attached property of the object is set to true. If the NotifyOnValidationError property of the Binding is set to true, then the binding engine raises the Validation::Error attached event on the object.
For a detailed discussion of the validation process, see the Data Validation section in the Data Binding Overview.
