Send listboxfor to controller












1















I have a form in my view that contains a listbox. The user adds values to the listbox.



When the user pushes the 'submit' button I want all the values in the listbox to be placed in my models property that is a List.



Here is the Listbox in my view:



 @Html.ListBoxFor(m => m.Ingredients, new List<Ingredient>(), new { @class = "form-control" , @id = "Ingredients"})


This line gives an error that is that the List has to contain SelectListItem. Even if i change to that, and also change it in my view model, it still doesn't work.



This is my viewmodel:



 public class RecipeModel
{
public int Id { get; set; }

public string Name { get; set; }

public List<Ingredient> Ingredients { get; set; }

public string Description { get; set; }

public string ImageUrl { get; set; }

public List<RecipeModel> Recipes { get; set; }
}


This is my controller:



[HttpPost]
public void SaveRecipe(RecipeModel model)
{
RecipeDb.SaveRecipe(Mapper.Map<Recipe>(model));
}


What I want is that in the controller, I want the models List Ingredients to be populated by all the items/values in the listbox from the view but I cant figure it out.

          A multiple select post back an array of simple values (say [1, 4, 7] or ["Recipe 2", "Recipe 4" ] depending on the values of the selected options). You cannot bind ListBoxFor to a collection of complex objects. Your view model needs to have a property to bind to. Assuming typeof Ingredient contains properties int ID and string Name, then you view model would be something like



          public class RecipeViewModel
          {
          public int SelectedIngredients { get; set; }
          public SelectList IngredientList { get; set; }
          }


          Then the controller



          public ActionResult Create()
          {
          RecipeViewModel model = new RecipeViewModel();
          // Populate the collection of available ingredients
          model.IngredientList = new SelectList(db.Ingredients, "ID", "Name");
          // if you want to pre select some options, then: model.SelectedIngredients = new int { 1, 4, 7 };
          return View(model);
          }

          [HttpPost]
          public ActionResult Create(RecipeViewModel model)
          {
          // model.SelectedIngredients will contain the ID's of the selected ingredients
          }


          And in the view



          @model RecipeViewModel
          @using(Html.BeginForm())
          {
          ....
          @Html.ListBoxFor(m => m.SelectedIngredients, Model.IngredientList)
