ValidationError validationError = new ValidationError(regexValidationRule, 
    textBox.GetBindingExpression(TextBox.TextProperty));

validationError.ErrorContent = "This is not a valid e-mail address";

Validation.MarkInvalid(
    textBox.GetBindingExpression(TextBox.TextProperty), 
    validationError);
