Passing JSON data from controller action to a razor view - asp.net

Question

I would like to know how can I pass data from controller to view in mvc3 razor.
The view is in .cshtml file.
I have a variable in the controller where I am storing the data I need to push to the listbox control in the view.
var results = data.Select(item => new { id = item, label = item.Value, value = item.Key });
Doing this:
return Json(results, JsonRequestBehavior.AllowGet);
Gives me only a popup with the data which needs to be pushed to the listbox:
In the view the listbox resides in accordion control:
<div id="accordion">
#{int i=0;}
#foreach (var item in Model.Parameters)
{
<h3>#Html.LabelFor(m => item.Name, item.Prompt)</h3>
<div>
<div class="editor-field">
<select multiple id="#("Select" +item.Name)" name="#("Select" +item.Name)"></select>
</div>
</div>
i++;
}
</div>
So, I would like to know what should I do to push the items to the listbox instead of showing a popup for the control
Beginner in MVC, Thanks for your understanding.
Thanks in advance, Laziale
EDIT: Json format output
{System.Linq.Enumerable.WhereSelectListIterator<System.Collections.Generic.KeyValuePair<string,string>,<>f__AnonymousType1<System.Collections.Generic.KeyValuePair<string,string>,string,string>>}

returning JSON to your razor view is probably not the best method. I would suggest use a viewModel which is a c# class by itself.
namespace Test
{
public class ViewModel
{
public bool GivingAPresentation { get; set; }
}
}
public class MyController: Controller
{
public virtual ActionResult Index()
{
var model=new ViewModel(){GivingAPresentation =true;}
return View(model);
}
}
Your view code:
#model Test.ViewModel <!-- Note the full namespace -->
<br>GivingAPresentation: #Model.GivingAPresentation </br>
If you are forced to work with a JSON object that is returned from your action then you need to deserialize it first and then work with that object. you can read this post http://www.drowningintechnicaldebt.com/ShawnWeisfeld/archive/2010/08/22/using-c-4.0-and-dynamic-to-parse-json.aspx on how to parse JSON to a c# dynamic object.
Let me know if that helps.
