List view? WPF, Forms, ASP.NET, what?!

Loop through those values(Array or something), check the ItemId is duplicate, if yes then SUM the qty values & Price values.

for(Condition)
{
 if(ItemId == TempItemId)//Check the ItemId for duplicate
 {
  //Sum those values
  Qty = Qty + TempQty;
  Price = Price + TempPrice;
  //Save into other object(Array or something), so you will get 3 rows instead of 5 rows finally
 }
}

Try that way also

var newI = items.GroupBy(i => i.ItemId).Distinct();

foreach (var item in newI)
{
       Response.Write(item.First() + "<BR/>");
}
