orderby および orderbydescending リスト関数を使用して並べ替えを行っていますが、読み取り専用のフィールドのみが正しく並べ替えられています。これを解決するのを手伝ってくれませんか。ありがとう。
コントローラーコード:
public ActionResult ProductList()
{
var productList = new ProductListViewModel();
productList.ProductItems = productRepository.GetProductsWithDeleteOption().ToList();
productList.CategoryItems = categoryRepository.GetCategories().ToList();
var sortList = GetSortList();
productList.SortByList = sortList;
productList.SelectedSortByValue = "ProductID";
return View(productList);
}
[HttpPost]
public ActionResult ProductList(ProductListViewModel productViewModel, FormCollection formCollection, string submit)
{
if (ModelState.IsValid)
{
var sortList = GetSortList();
productViewModel.SortByList = sortList;
productViewModel.CategoryItems = categoryRepository.GetCategories().ToList();
productViewModel.SortByList = sortList;
// Check for submit action
if (submit == "Change Sort")
{
if (formCollection["SortDirection"] == "Desc")
{
switch (productViewModel.SelectedSortByValue)

@for (var i = 0; i < Model.ProductItems.Count; i++)
