Question

In ASP.net MVC:

How should/Can I pass Form data (From the View) to the Controller?

This is the way I am heading :

• The Controller Index function is passing a ViewModel object to the View.
• The ViewModel object contains a paginated list as well as some SelectLists. _ The ViewModel object also contains a custom class I named theFilter. This class’ purpose is to hold the Filter information Posted from the View via a Form.
• I want the Index [AcceptVerbs(HttpVerbs.Post)] function to receive theFilter object populated with the form data, as well as the page number (as is it right now)

Here are snippets of my code:

The Controller/Index postback function:

    [AcceptVerbs(HttpVerbs.Post)]     public ActionResult Index(int? page, CaseFilter caseFilter)     {         const int pageSize = 10;         var cases = caseRepo.FindAllCases();         var paginatedCases = new PaginatedList<Case>(cases, page ?? 0, pageSize);         return View(new CaseIndexViewModel(paginatedCases, caseFilter));     } 

The Filter Class:

public class CaseFilter {     int iVolume_id = 0,         iSubject_id = 0;      public CaseFilter() {      }      public int Volume_id { get { return iVolume_id; } set { iVolume_id = value; } }     public int Subject_id { get { return iSubject_id; } set { iSubject_id = value; } }  } 

And the ViewModel class:

    public class CaseIndexViewModel     {     public PaginatedList<Case> PaginatedCases { get; private set; }     public CaseFilter CaseFilter { get; private set; }      public CaseIndexViewModel(PaginatedList<Case> paginatedCases, CaseFilter caseFilter)     {         PaginatedCases = paginatedCases;        CaseFilter = caseFilter;     } } 

Basically I am trying to avoid using Request.Form to populate the Filter class, at least not to use it within the Controller.

Any help, suggestions or disses are welcome!

Finally, I do not need to even use the Request Collection. The CaseFilter object is filled automatically as I set it as a parameter in

public ActionResult Index(int? page, CaseFilter caseFilter) 

The code above works as it is.
