Html Dropdownlist helper binding issue after post request

Question

Hi Friends ,

I am stuck into the situation known as

(Index was out of range. Must be non-negative and less than the size of the collection.) for Html Dropdownlist

This Exception raises when i post a request in asp.net mvc to an action method it keeps on giving me above error

 

View 

 

@using PagedList;

@using PagedList.Mvc;

@model IPagedList<Models.Prices>

 

  @Html.DropDownList("Id", new SelectList((List<SelectListItem>)ViewBag.Id, "Value", "Text"), "Select")

 

Controller

 

[Authorize]

[HttpPost]

public ActionResult Base(Prices prices, int? page)

{

   prices.commodity = ListCommodities(2);

   ViewBag.Id = prices.commodity;

   List<Prices > lstPrices = new List<Prices >();

   lstPrices

= ListPrices (prices.marketid, prices.Id,prices.exchangeid, 0, prices.fromdate,    prices.todate);

   var lstPrices1 = lstPrices.ToPagedList(page ?? 1, 10);

   return View(lstPrices);

}

 //Method to get Commodities

public List<SelectListItem> ListCommodities(int id)

{

Prices prices = new Prices();

List<SelectListItem> lstCommodities = new List<SelectListItem>();

DataTable dt = DAL.PricesDAL.ListCommodities(id);

if (dt != null)

{

if (dt.Rows.Count > 0)

{

foreach (DataRow dr in dt.Rows)

{

lstCommodities.Add(new SelectListItem() { Value = dr["Id"].ToString(), Text = dr["Product"].ToString() });

}

}

}

return lstCommodities;

}
