Using Foolproof RequiredIf on multiplecondition

I have a dropdownlist named CustomerType with the the following values

Id     Name
1      Student
2      Non-Employed
3      Employed
4      SelfEmployed

and I have one more property in my viewmodel public string CompanyAddress{ get; set; }

My goal is to make CompanyAddress required if dropdownlist has values 3 or 4

I have tried the following but gets error Cannon have duplicate RequiredIf

    [RequiredIf("customerTypeID", 3, ErrorMessage = "Please enter company address")]
    [RequiredIf("customerTypeID", 4, ErrorMessage = "Please enter company address")]
    public string CompanyAddress { get; set; }

For the "TypeError: Cannot read properties of undefined (reading 'value')" problem, add a hidden input element on your page for that new CompanyAddressRequired property.

<input type="hidden" id="CompanyAddressRequired"/>

I'm still working on getting the switchable field to provide validation summaries on my front end but this resolves the JS error.

This will put logic in your model (which is usually a no-no), but it will work. You could change your validation to be like this:

[RequiredIf("CompanyAddressRequired", true, ErrorMessage = "Please enter company address")]

And then have a property with a getter like this:

public bool CompanyAddressRequired
{
    get
    {
        return customerTypeID == 3 || customerTypeID == 4;
    }
}
