Hi All,

I have added a custom email field to the member type. I am validating the member email with the custom email field for login. So I need to show a validation message in the Umbraco backend for already existing email while creating a new Umbraco member.

I am trying with the code below but it is not working as expected

private void MemberSaving(IMemberService sender, Umbraco.Core.Events.SaveEventArgs<IMember> e)
        {
            Random randomNumber = new Random();
            var umbracoHelper = new UmbracoHelper(UmbracoContext.Current);
            foreach (var memberItem in e.SavedEntities)
            {
                if (memberItem.ContentType.Alias == "Member")
                {
                    var Email = memberItem.Email;
                    var AdditionalEmail = memberItem.GetValue<string>("additionalEmail");
                    var IsExist = _memberService.GetByEmail(AdditionalEmail);
                    if ((string.IsNullOrWhiteSpace(Email.ToLower()) == string.IsNullOrWhiteSpace(AdditionalEmail.ToLower())) || IsExist!=null)
                    {
                        e.Cancel = true;                    
                        e.Messages.Add(new EventMessage("Invalid email", "You can not add already existing email...", EventMessageType.Success));

            }
       }
   }
}

Please help to find a solution for this

Thank You
