Question

I have a message board in ASP.Net MVC and when the user creates a new Post they must select a category, when I create a view (Create) the field (Categories) doesnt appear?

The database has a middle table MessageToCatRel which contains a messageID and a CatId. I think this is what is confusing MVC. At the moment i am doing the following, but dont like the idea of using the Request.Form. How can I get it to post back in the Object like the other fields?

  public ActionResult Create(Message messageToCreate) //Post back from Message Post
            {
                if (!ModelState.IsValid)
                {
                    this.LoadCategoryViewData();
                    return View();
                }

                //Now try and save this in the Database     /

/And Save
                IMessageRepository repo = new MessageRepository();
                MessageCategory curCatRel = new MessageCategory();
                curCatRel.CategoryID = Convert.ToInt32(Request.Form["Categories"]);

                messageToCreate.MessageCategories.Add(curCatRel);
                messageToCreate.CreatedBy = 1; //Temp messure
                messageToCreate.PublishDateTime = DateTime.Now;

                repo.AddMessage(messageToCreate);
                repo.Save();

Thanks for the reply, doesnt really do what I wanted. I’m sticking to use ViewData for a bit.

Thanks
