Question

I have been stuck on this problem for too long and would love some help.

On a view people can select two items from two radiobutton lists which returns via a FormMethod.Get to the Index event in HomeController.

These 2 values, ‘parts and ‘use’ are queried to return a result and its passed back to the view via a viewbag. However the viewbag returns a line like { Item = Kona, Price = 400.0000, Quantity = 2 } in the view.

Whereas I want to return each item such as item.Item, Item.Price so I can use them individually.

I have tried everything I can find to no avail.
Anonymous classes items also throw red errors

View

foreach(var item in ViewBag.getstock)
{ //Show it and then make a new line with the <BR/>
    @item < br / >
    //{ Item = Kona, Price = 400.0000, Quantity = 2 } 
}

HomeController

 public ActionResult Index()
 {
     //this returns the entire query string
     ViewBag.querystring = Request.QueryString;

     //if any keys are in the url from the view
     if (Request.QueryString.HasKeys())
     {
         //extract them out so that you can use them
         //key = the name such as Part or Use it goes Key & Value this is passed to a Viewbag
         //get(o) is getting the value at place 0, the first value in the url

         ViewBag.querystringvalue0 = Request.QueryString.Get(0);
         ViewBag.querystringvalue1 = Request.QueryString.Get(1);
     }

     //if there is any query string
     if (Request.QueryString.HasKeys())
     {
         //pass the data to a couple of variables,
         var parts = Request.QueryString.Get(0);
         var use = Request.QueryString.Get(1);

         //put them in a new query and return the results
         ViewBag.getstock = from p in Bikeshopdb.Stocks
         where p.PartName == parts && (p.Road == use || p.Mtn == use || p.Hybrid == use) select new
         {
             p.Item, p.Price, p.Quantity
         };

     }
     return View(Bikeshopdb.Stocks.ToList());

Use a ViewModel class to hold the query results and pass back to the view. For example:

HomeController

public class MatchingStock()
{

    public int ID { get; set; }
    public string Item { get; set; }
    public int Price { get; set; }
    public int Quantity { get; set; }

}

public ActionResult Index()
{

    //...

    var list = 
        (from p in Bikeshopdb.Stocks
        where p.PartName == parts && 
            (p.Road == use || p.Mtn == use || p.Hybrid == use)
        select new MatchingStock() { 
            ID = p.ID, 
            Item = p.Item, 
            Price = p.Price, 
            Quantity = p.Quantity}).ToList();

    ViewBag.getstock = list;

    //...

}

View

@foreach (var item in (List<MatchingStock>)ViewBag.getstock)
{
    @item.Item @item.Price @item.Quantity
    <br />
}
