Question

My action accepts a model that looks like the following:

public class ClassListVM
{
    public ClassListVM()
    {
        Filter = new ClassFilterModel();
    }

    public ClassFilterModel Filter { get; set; }
    public PagedList<Class> Classes { get; set; }
}

public class ClassFilterModel
{
    public int? TermId { get; set; }
    public int? SubFormId { get; set; }
    public int? FormId { get; set; }
}

public ActionResult Index(ClassListVM model)
{
    model.Classes = classService.GetClasses(model.Filter);
    return View(model);
}

Now I want to generate a url like this: /Classes?Filter.SubFormId=1. How do I get the Filter part into the url using this code:

<a href="@Url.Action("Details", "Classes", new {Filter.TermId = Model.TermId, Filter.SubFormId = subForm.SubFormId})">go</a>

As you can see, Filter cannot be used here.

Answer 1

Theoretically, you can build it this way:

<a href="@Url.Action("Details", "Classes")?Filter.TermId=@Model.TermId&amp;Filter.SubFormId=@subForm.SubFormId">go</a>

Something like that; essentially, embed the query string into the client markup, and inject in only the parameters.
