How to call object from Controller to display in the View of ASP.net MVC - asp.net-mvc-2

Question

I have one action in my controller :
public ActionResult GiftVochure()
{
if (Request.QueryString["gc"] != "")
{
var obj = from b in context.GiftCards
join cus in context.Customers on b.CustomerID equals cus.ID
where b.ID == int.Parse(Request.QueryString["gc"])
select new
{
b.ID,
b.Date,
b.CardNo,
b.Price,
CustomerName = cus.FirstName + " " + cus.LastName
};
return View(obj.ToList());
}
return View();
}
And I want to take "obj" to loop and display in the GiftVochure Views, Does any one know, how to do this?
Thanks.

You should start by defining a model type to replace the anonymous type projected by the query.
public class CardInfo
{
int ID { get; set; }
DateTime Date { get; set; }
int CardNo { get; set; }
double Price { get; set; }
string CustomerName { get; set; }
}
Modifying your action method:
var obj = from b in context.GiftCards
join cus in context.Customers on b.CustomerID equals cus.ID
where b.ID == int.Parse(Request.QueryString["gc"])
select new CardInfo
{
ID = b.ID,
Date = b.Date,
CardNo = b.CardNo,
Price = b.Price,
CustomerName = cus.FirstName + " " + cus.LastName
};
return View(obj);
Then you should strongly type your GiftVochure view to this type's sequence.
#model IEnumerable<CardInfo>
In the end you can iterate the items in your view.
#foreach(CardInfo current in Model) {
//display info
}
You should probably move your markup for displaying a single object to a partial view. Then render it in your loop.
