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.
