MVC3

Dear Friends,

I have developed items screen, i created view with two tables in database and retrieve values from view to update the values.

But it makes an error:
The model item passed into the dictionary is of type telecom.models.itemrates, but this dictionary requires a model item of type telecom.models.vw_items

What I have tried:

Model:
public class Vw_Items
{
public int Id { get; set; }
public string RateCode { get; set; }
public string ItemCode { get; set; }
[DisplayName("Item Name")]
public string ItemName { get; set; }
[DisplayName("Item Type")]
public string ItemType { get; set; }
public string UOM { get; set; }
[Required]
[DisplayName("Unit Price")]
public decimal? UnitPrice { get; set; }
}
Controller:

[HttpPost]
public ActionResult Edit(ItemRates itemrates)
{
if (ModelState.IsValid)
{
db.Entry(itemrates).State = EntityState.Modified;
db.SaveChanges();
return RedirectToAction("Index");
}
return View(itemrates);
}
View:
@model Telecom.Models.Vw_Items
