custom property with RequiredIf

[JasonLounsbery]

I have a property that determines if a field is required. It always says it is required

    [DataMember]
     [Description("Address Line 1")]
    [RequiredIf("isRequired(ADDRESS,'STREET') == true", ErrorMessage="Address is Required")]
    public string ADDRESS { get; set; }

[DataMember] [Description("Address Line 2")] [RequiredIf("isRequired(ADDRESS2,'STREET2') ", ErrorMessage = "Address is Required")] public string ADDRESS2 { get; set; }

public bool isRequired(string value,string FieldName) { return false;

    }

I removed the code for IsRequired so it always returns false

ADDRESS and ADDRESS2 are always required. Can something like this be done?

The issue is that the properties are being flagged as required regardless of what IsRequired is returning. I thought that the RequiredIf attribute would reflect what ever the function IsRequired returned. If IsRequred returns True and the Address field is blank, the error message shows up. if IsRequred returns False, and the Address field is blank, the error message shows up.

Here is my code. For testing I have isRequired returning false.

…Model

[DataMember] [Description("Address Line 2")] [RequiredIf("isRequired(ADDRESS2,'STREET2') ", ErrorMessage = "Address is Required")] public string ADDRESS2 { get; set; }

public bool isRequired(string value,string FieldName) { return false; }

You should probably take a look at the documentation related to defining your own methods - if you are using client-side validation you need to define respective method at client-side as well. I assume you have an error related to undefined reference - check your web console output.

Also, I advise you to use GitHub directly instead of emails when posting here, because you have the opportunity to format your messages using markdown.
