ビューコードの引数strをコントローラに渡すことができません。それはヌルとして終わる。私はそれを ""として渡したい。アクションリンク引数がコントローラに正しく渡されない
助けが必要ですか？
コントローラコード：
public ActionResult Index(string str, string sortOrder)
{
if (str == "")
return View(db.Ports.OrderByDescending(model => model.PurchaseDate));
ViewBag.NameSortParm = String.IsNullOrEmpty(sortOrder) ? "name_desc" : "";
ViewBag.DateSortParm = sortOrder == "Date" ? "date_desc" : "Date";
var investments = from s in context.Investments
select s;
switch (sortOrder)
{
case "name_desc":
investments = investments.OrderByDescending(s => s.LastName);
break;
case "Date":
investments = investments.OrderBy(s => s.PurchaseDate);
break;
case "date_desc":
investments = investments.OrderByDescending(s => s.PurchaseDate);
break;
default:
investments = investments.OrderBy(s => s.LastName);
break;
}
return View(investments.ToList());
}
コードの表示：
@model StockHoldings.Models.Investments
@{
ViewBag.Title = "Create";
}
<h2>Create</h2>
