Question

So I have the following code:

@model Project.Models.ViewModels.SomeViewModel
@using (Html.BeginForm("SomeAction", "SomeController", new { id = Model.Id}))
        {
            for(int i = 0; i < Model.SomeCollection.Count(); i++)
            {
                @Html.HiddenFor(x => Model.SomeCollection.ElementAt(i).Id)
                <div class="grid_6">
                    @Html.TextAreaFor(x => Model.SomeCollection.ElementAt(i).Text, new { @style = "height:150px", @class = "grid_6 input" })
                </div>
            }
            <div class="grid_6 alpha omega">
                <input type="submit" value="Next" class="grid_6 alpha omega button drop_4 gravity_5" />
            </div>
        }

On the Controller Side I have the following:

[HttpPost]
        public ActionResult SomeAction(int id, SomeViewModel model)
        {

            return PartialView("_SomeOtherView", new SomeOtherViewModel(id));
        }

My View Model is set up like this:

public class SomeViewModel
{
        public SomeViewModel()
        {

        }
        public IEnumerable<ItemViewModel> SomeCollection { get; set; }

}

public class ItemViewModel{

      public ItemViewModel(){}

      public int Id {get;set;}

      public string Text{get;set;}

}

The SomeCollection is always empty when SomeAction if performed. What do I have to do in order to show the updated values by users. Text Property and Id field.

Answer 1

Use an EditorTemplate

Create an EditorTemplate folder under your Views/YourcontrollerName and create a view with name ItemViewModel.cshtml

And Have this code in that file

@model  Project.Models.ViewModels.ItemViewModel
<p>
 @Html.EditorFor(x => x.Text) 
 @Html.HiddenFor(x=>x.Id)
</p>

Now from your Main view, call it like this

@model  Project.Models.ViewModels.SomeViewModel
@using (Html.BeginForm("SomeAction", "Home", new { id = Model.Id}))
{
    @Html.EditorFor(s=>s.SomeCollection)
    <div class="grid_6 alpha omega">
        <input type="submit" value="Next" class="grid_6 alpha omega button drop_4 gravity_5" />
    </div>
}

Now in your HTTPPOST method will be filled with values.

I am not sure what you want to do with the values( returning the partial view ?) So not making any comments about that.
