我想列出使用pagedlist在asp.net mvc中开发的页面中的所有项目。它完成了。我想更新所有或选定的项目。可以列出并且只能选择所选项目但不能将模型发布到控制器。在更新按钮后，我可以发布模型，但不能发布值，它是空的。任何人都可以帮忙吗？
我的控制器：
namespace Management.Controllers
{
public ActionResult ListDebts(string sortOrder, string currentFilter,
string searchString, string Part,string Term, string PayStat, int? page, bool? checkboxes)
{
ViewBag.CurrentSort = sortOrder;

ViewBag.DueDateSortList = sortOrder == "Date" ? "date_desc" : "Date";
ViewBag.AmountSortList = sortOrder == "Amount" ? "amount_desc" : "Amount";
if (searchString != null)
{
page = 1;
}
else
{
searchString = currentFilter;
}
ViewBag.CurrentFilter = searchString;
var debts = from d in db.Debts
select d;
if (!String.IsNullOrEmpty(searchString))
{
debts = debts.Where(d => d.DebtPart.PartitionName.Equals(searchString));
