asp.net-mvc-3 - ネストされた GridView のコンテンツによって親 Gridview の項目 ID を呼び出す方法

Question

ネストされた列の親ソースの PkId を Nestgrd.Column("Qty", format: (item) => Html.ActionLink((string)item.Product.ToString(), "FreeGiftQuantityViews", new { id = item.PkId } を呼び出すことができません. new { id = item.PkId } を new {id= pkglist.item.PkId} として呼び出すにはどうすればよいですか?

<div id="lgrid" class="tablesorter">
    @{

        var grid = new WebGrid(Model.pkglist, rowsPerPage: 10, canSort: false, canPage: false, ajaxUpdateContainerId: "lgrid");

    }

@grid.GetHtml(
    tableStyle: "lgrid",
    headerStyle: "head",
    alternatingRowStyle: "alt",
    columns: grid.Columns(
    grid.Column("S.N.", format: @<text>@{count++;}@count</text>, style: "sn"),
    grid.Column("PkId", format: @<text>@item.PkId</text>),
    grid.Column("Package Name", format: @<text>@item.PackageName</text>),
    grid.Column("Product", format: @<text>@item.Product</text>),
    grid.Column("Access", format: @<text>@item.Access</text>),
    grid.Column("Rate", format: @<text>@item.Rate</text>),
    grid.Column("Remarks", format: @<text>@item.Remarks</text>),
    grid.Column("Edit", format: (item) => Html.ActionLink("Edit", "EditPackage", new { id = item.PkId }, new { @class = "openDialog", data_dialog_id = "emailDialog", data_dialog_title = "Edit" })),
    grid.Column("Delete", format: (item) => Html.ActionLink("Delete", "DeletePackage", new { id = item.PkId }, new { @class = "openDialog", data_dialog_id = "emailDialog", data_dialog_title = "Delete" })),
    grid.Column("Free Package Lists", format: row =>
        {
            WebGrid nestgrd = new WebGrid(row.plsst);
            return nestgrd.GetHtml(
                columns: nestgrd.Columns(
                    nestgrd.Column("FreePackageDetails", format: (item) => Html.ActionLink((string)item.Product.ToString(), "FreePackageDetails", new { id = item.PkId }, new { @class = "openDialog", data_dialog_id = "EmailDialog", data_dialog_title = "Details" })),
                    nestgrd.Column("Free Gift", format: (item) => Html.ActionLink((string)item.Product.ToString(), "FreeGiftViews", new { id = item.PkId }, new { @class = "openDialog", data_dialog_id = "EmailDialog", data_dialog_title = "Details" })),
                    nestgrd.Column("Qty", format: (item) => Html.ActionLink((string)item.Product.ToString(), "FreeGiftQuantityViews", new { id = item.PkId }, new { @class = "openDialog", data_dialog_id = "EmailDialog", data_dialog_title = "Details" }))


                ),
                displayHeader: false
            );
        })
                                                                                                                          ))
</div>
