ドロップダウンリストを表示する更新可能な外部キー列を持つAjaxTelerikグリッドをRazorで作成しようとしています。例のようにページをコピーしましたが、すべてが機能します。新しいレコードを追加、削除、編集できます。動作しない唯一のことは、グリッド内のレコードを更新するときに、外部キーテーブルのすべての可能性を含むドロップダウンリストではなく、整数のテキストフィールドを取得することです。

誰かが私がこれを修正する方法について何かアイデアがありますか？以下のコードを参照してください。

Telerikグリッド：

@(Html.Telerik().Grid<EditableAccount>()
    .Name("Grid")
    .ToolBar(commands => commands.Insert().ButtonType(GridButtonType.Text).ImageHtmlAttributes(new { style = "margin-left:0" }))
    .DataBinding(dataBinding => dataBinding.Ajax()
        .Insert("InsertAccount", "Administration")
        .Update("SaveAccount", "Administration")
        .Delete("DeleteAccount", "Administration"))
    .DataKeys(keys => { keys.Add(a => a.AccountId); })
    .Columns(columns =>
    {
        columns.ForeignKey(b => b.BankId, (IEnumerable)ViewData["Banks"], "ID", "Name").Width(50);
        columns.Bound(a => a.AccountNumber).Width(110);
        columns.Command(commands =>
        {
            commands.Edit().ButtonType(GridButtonType.Image);
            commands.Delete().ButtonType(GridButtonType.Image);
        }).Width(16);
    })
    .Editable(editing => editing.Mode(GridEditMode.InLine))
    .Pageable()
    .Scrollable()
    .Sortable()
)

コントローラ：

[GridAction]
public ActionResult Accounts()
{
    ViewData["Banks"] = db.Banks.Select(b => new { Id = b.BankId, Name = b.Name });
    return View(new GridModel(accountRepository.All()));
}

[AcceptVerbs(HttpVerbs.Post)]
[GridAction]
public ActionResult InsertAccount()
{
    //Create a new instance of the EditableProduct class.
    EditableAccount account = new EditableAccount();

    //Perform model binding (fill the product properties and validate it).
    if (TryUpdateModel(account))
    {
        //The model is valid - insert the product.
        accountRepository.Insert(account);
    }

    //Rebind the grid
    return View(new GridModel(accountRepository.All()));
}

[AcceptVerbs(HttpVerbs.Post)]
[GridAction]
public ActionResult SaveAccount(int id, int bankId)
{
    EditableAccount account = new EditableAccount
    {
        AccountId = id,
        Bank = db.Banks
                   .Where(b => b.BankId == bankId)
                   .Select(b => b.Name).SingleOrDefault(),
        BankId = bankId
    };

    TryUpdateModel(account);

    accountRepository.Update(account);

    return View(new GridModel(accountRepository.All()));
}

[AcceptVerbs(HttpVerbs.Post)]
[GridAction]
public ActionResult DeleteAccount(int id)
{
    //Find a customer with ProductID equal to the id action parameter
    EditableAccount account = accountRepository.One(a => a.AccountId == id);

    if (account != null)
    {
        //Delete the record
        accountRepository.Delete(account);
    }

    //Rebind the grid
    return View(new GridModel(accountRepository.All()));
}

モデル：

public class EditableAccount
{
    [ScaffoldColumn(false)]
    public int AccountId { get; set; }

    [Required]
    [UIHint("GridForeignKey")]
    [DisplayName("Bank")]
    public int BankId { get; set; }
    public string Bank { get; set; }

    [Required]
    [DisplayName("AccountNumber")]
    public int AccountNumber { get; set; }
}

public IList<EditableAccount> All()
{
    IList<EditableAccount> result =
            (from account in db.Accounts
             select new EditableAccount

                 AccountId = account.AccountId,
                 Bank = account.Bank.Name,
                 BankId = account.BankId,
