Property Value

Type: System::Boolean

true if the Validation::Error event occurs when the state of a ValidationRule changes; otherwise, false. The default is false.

The Validation::Error attached event occurs on the element that has the BindingGroup.

The following example creates a BindingGroup and sets NotifyOnValidationError to true so that the application can handle the Validation::Error event when a ValidationRule fails.

<StackPanel.BindingGroup>
  <BindingGroup NotifyOnValidationError="True">
    <BindingGroup.ValidationRules>
      <src:ValidateDateAndPrice ValidationStep="ConvertedProposedValue" />
    </BindingGroup.ValidationRules>
  </BindingGroup>
</StackPanel.BindingGroup>

The following example handles the Validation::Error event.
