How we can create a custom model validation with both client side and server side validation in asp.net core. My requirement is to check the value of a property and if it satisfies the value, the required field should be enabled. other wise disable. The annotation can also be applied on object properties.Like this.

      public class TradeModel
        {  

    public bool TradingObjectives { get; set; }

  [RequiredIf("TradingObjectives","true",ErrorMessage="required")]

    public int Hedge{ get; set; }

    [RequiredIf("TradingObjectives","true",ErrorMessage="required")]

    public AddressModel Address{ get; set; }

     }

          public class AddressModel 
           {
            public long AddressId { get; set; }

            [Required]
            public string Address1 { get; set; }

            public string Address2 { get; set; }
      }

I think you should use Fluent Validation for custom validators. And you can add client-side support to Fluent Validation with FormHelper.

You can write custom validators, even database queries. It's an amazing solution for you.
