Question

I have this code that creates an url

<a href="ContactInformation/CreateContactInformation/dossierId=@Model.DossierId" class="ContactInformationEdit">Add New</a>

(I couldnt find out how to make an actionlink that used an action, controller, object and where I could put a classname on for use in javascript)

That gives a link like this http://localhost:51730/ContactInformation/CreateContactInformation/dossierId=1

I then have a controller action

[HttpGet]
    public ActionResult CreateContactInformation(int? dossierId)
    {
        return PartialView("ContactInformationCreate", new ContactInformationViewModel(dossierId.Value));
    }

But if I put a breakpoint in that code then the variable is just “null” doing a request param gives same result

Answer 1

<a href="ContactInformation/CreateContactInformation/?dossierId=@Model.DossierId" class="ContactInformationEdit">Add New</a>

i.e. You missed the ? before your query string
