Take a look on this code.

    [AttributeUsage(AttributeTargets.Property | AttributeTargets.Field | AttributeTargets.Parameter, AllowMultiple = false)]
public class RequiredIfAttribute : RequiredAttribute
{
    public string PropertyName { get; set; }
    public Enums.BasicOperationType BasicOperationType { get; set; }

    public RequiredIfAttribute(string propertyName, Enums.BasicOperationType BasicOperationType)
    {
        this.PropertyName = propertyName;
        this.BasicOperationType = BasicOperationType;
    }

    protected override ValidationResult IsValid(object value, ValidationContext validationContext)
    {
        Type objectType = validationContext.ObjectType;
        PropertyInfo[] neededProperties = objectType.GetProperties().Where(propertyInfo => propertyInfo.Name == PropertyName).ToArray();
        if (Core.Helpers.EnumHelper.TryParse(Convert.ToInt16(neededProperties[0].GetValue(validationContext.ObjectInstance, null))) == BasicOperationType)
            return base.IsValid(value, validationContext);

        return base.IsValid(0, validationContext);
    }
}
