Problems reading http get var from url in mvc 3

Question

I have this code that creates an url

<a href="ContactInformation/CreateContactInformation/[email protected]" 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

<a href="ContactInformation/CreateContactInformation/[email protected]" class="ContactInformationEdit">Add New</a>

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

ContactInformation/CreateContactInformation/[email protected]

Should be

ContactInformation/[email protected]

Url.Action helper is used to generate only link. And you could use that link in whatever you like, anchor or anything else. But there also is builtin ActionLink overload to generate exactly what you want.

@Html.ActionLink("Add New", "CreateContactInformation", "ContactInformation", new {dossierId = @Model.DossierId}, new {@class="ContactInformationEdit"})

Code above will regard your route configuration too

Have you got the routing right?

routes.MapRoute( _
"ContactInformation" _
"ContactInformation/CreateContactInformation/{parameters}" _
new With { .controller = "ContactInformation", .action = "CreateContactInformation"})

And then

<a href="ContactInformation/[email protected]" class="ContactInformationEdit">Add New</a>
