子网格上的外键列使模板无效

Question

我有以下Kendo网格，这是我的主要网格：

@using Resources;
@using ITSV6.ElysiumDataService;
@using Kendo.Mvc.UI.Html;
@using System.Web.Mvc;

@{
    ViewBag.Title = Resource.PayRules;
    Layout = "~/Views/Shared/_Layout.cshtml";
    var Holidays = (IEnumerable<att_holidays>)ViewData["Holidays"];

    var PayCodes = (IEnumerable<att_pay_codes>)ViewData["PayCodes"];
}

<div class="row">
    @(Html.Kendo().Grid<att_pay_rules>()
                    .Name("GridPayRuleDefinition")
                    .Columns(columns =>
                    {
                        columns.Bound(p => p.pr_pay_rule).Hidden();
                        columns.Bound(p => p.pr_name).Title(Resource.Name).Width("").Filterable(ftb => ftb.Cell(cell => cell.Operator("contains").ShowOperators(false)).Extra(false));
                        columns.Bound(p => p.att_fixed_rules.fr_name).Title(Resource.FixedRule).Width("").Filterable(ftb => ftb.Cell(cell => cell.Operator("contains").ShowOperators(false)).Multi(true));
                        columns.ForeignKey(m => m.tr_terminal_rule, (IEnumerable<att_terminal_rules>)ViewData["Terminals"], "tr_terminal_rule", "tr_name")
                           .HtmlAttributes(new { data_value_primitive = "true" })
                           .Title(@Resource.TerminalRule);

                        .Title(Resource.LaborDayHours)
                        .HeaderHtmlAttributes(new { @style = "text-align:right;" }).HtmlAttributes(new { align = "right" })
                        .Width("").Filterable(ftb => ftb.Cell(cell => cell.Operator("contains").ShowOperators(false)).Multi(true));
                        columns.Command(command =>
                        {
                            command.Custom("Copy").Text(" ").SendDataKeys(true).Click("copyGridRecord").HtmlAttributes(new { @class = "fa fa-files-o fa-lg", title = Resource.Duplicate + " " + Resource.PayRule });
                            command.Edit().Text(" ").HtmlAttributes(new { title = Resource.Edit + " " + Resource.PayRule });
                            command.Destroy().Text(" ").HtmlAttributes(new { title = Resource.Delete + " " + Resource.PayRule });
                        }).Width(140);

            .ToolBar(toolbar => toolbar.Create().Text(Resource.AddNewPayRule))

            .ToolBar(toolbar => toolbar.Excel().HtmlAttributes(new { @class = "iconExcel" }))
            .Editable(editable => editable.Mode(GridEditMode.PopUp).TemplateName("payRuleDefinition").Window(w =>
            {
                w.Width(485);
                w.Title(Resource.PayRule + " " + Resource.Editor);
            }
                ))
            .Excel(excel => excel.FileName("PayRules.xlsx").ProxyURL(Url.Action("Excel_Export_Save", "Pay Rules")).Filterable(true).AllPages(true))
            .Pageable()

            .Editable(e => e.DisplayDeleteConfirmation(false))
            .Scrollable(a => a.Height("100%"))
            .Filterable(ftb => ftb.Mode(GridFilterMode.Menu))
            .ClientDetailTemplateId("subgrid")
            .DataSource(dataSource => dataSource
                .Ajax()
                .PageSize(20)

                .Model(model =>
                {
                    model.Id(pk => pk.pr_pay_rule);
                    model.Field(f => f.att_fixed_rules).DefaultValue(new att_fixed_rules());
                    model.Field(f => f.att_terminal_rules).DefaultValue(new att_terminal_rules());
                    model.Field(f => f.att_work_rules).DefaultValue(new att_work_rules());

                })
                .Create(update => update.Action("Create", "PayRuleDefinition"))
                .Read(read => read.Action("Read", "PayRuleDefinition"))
                .Update(update => update.Action("Update", "PayRuleDefinition").Data("ConvertDates"))
                .Destroy(destroy => destroy.Action("Destroy", "PayRuleDefinition"))
                .Events(ev => ev.Error("handleGridPayRuleDefinition")

            )
            .Events(e =>
            {
                e.Remove("function(args){gridRecord_Remove(args,'GridPayRuleDefinition');}");

            })
)
</div>

结果看起来像这样 - 链接添加，我没有足够的“声望点”附加图像，抱歉）：Main-Grid

该网格包含信息记录。左侧的每条记录都有一个“+”按钮，该按钮应显示带有Holiday记录的子网格，可以在InLine模式下进行编辑。子网格的代码看起来像这样：

<script id="subgrid" type="text/kendo-tmpl">
    @(Html.Kendo().Grid<att_pay_rules_holidays>()
        .Name("grid_#=pr_pay_rule#")
        .Columns(columns =>
        {
            columns.Bound(c => c.pr_pay_rule).Hidden();
            columns.ForeignKey(m => m.hdy_holiday, (IEnumerable<att_holidays>)ViewData["Holidays"], "hdy_holiday", "hdy_name")
                    .HtmlAttributes(new { data_value_primitive = "true" })
                    .Title(@Resource.Holiday).Width("30%");
            columns.ForeignKey(m => m.pc_pay_code, (IEnumerable<att_pay_codes>)ViewData["PayCodes"], "pc_pay_code", "pc_name")
                    .HtmlAttributes(new { data_value_primitive = "true" })
                    .Title(@Resource.PayCodes).Width("30%");
            columns.Bound(c => c.prh_time_payed).Title(Resource.Hours).Width("20%");
            columns.Command(cmd =>
            {
                cmd.Edit().Text(" ").CancelText(" ").UpdateText(" ").HtmlAttributes(new { title = Resource.Edit + " " + Resource.LaborAccount + " " + Resource.Entry });
                cmd.Destroy().Text(" ").HtmlAttributes(new { title = Resource.Delete + " " + Resource.LaborAccount + " " + Resource.Entry });
            }).Width("15%");
        })
       .ToolBar(toolbar => toolbar.Create().Text(" " + Resource.Add + " " + Resource.New + " " + Resource.Holiday).HtmlAttributes(new { @class = "iconAdd" }))
       .Editable(e => e.DisplayDeleteConfirmation(false))
       .Editable(editable => editable.Mode(GridEditMode.InLine))
       .Events(ev => ev.Remove("function(args){ gridRecord_Remove(args,'grid_#=pr_pay_rule#');}"))
       .Pageable()
       .Filterable(ftb => ftb.Mode(GridFilterMode.Menu))
       .Sortable()
       .DataSource(ds => ds
               .Ajax()
               .Model(model =>
               {
                   model.Id(p => p.pr_pay_rule);
               })
               .Read(read => read.Action("ReadHoliday", "PayRuleDefinition").Data("getRulesHolidaysData(#=pr_pay_rule#)"))
               .Update(update => update.Action("UpdateHoliday", "PayRuleDefinition"))
               .Create(update => update.Action("CreateHoliday", "PayRuleDefinition").Data("function(args){AssignPayRule(args,#=pr_pay_rule#)}"))
               .Destroy(destroy => destroy.Action("DestroyHoliday", "PayRuleDefinition"))
               .Events(ev => ev.Error("function(args){handleGridError(args, 'grid_#=pr_pay_rule#')}"))
       )
       .Events(e =>
       {
           e.Remove("function(args){gridRecord_Remove(args,'grid_#=pr_pay_rule#');}");
       })
       .ToClientTemplate()
)
</script>

结果如下：Sub-Grid displayed

子网格应包含有关Holidays信息的记录。如您所见，外键列填充如下：

columns.ForeignKey(m => m.hdy_holiday, (IEnumerable<att_holidays>)ViewData["Holidays"], "hdy_holiday", "hdy_name")

问题是当我点击主网格中任何一个记录中的“+”按钮时，子网格变得无效，我猜是由于外键列。如果我在尝试显示Holiday记录时打开Goog​​le Chrome控制台，则会出现“Uncaught SyntaxError：Invalid or unexpected token”错误。当正在编辑Holiday记录或正在创建新的PayCode记录时，子网格上的每个外键列都应生成带有Holiday和Holiday选项的DropDownList。但这不是正在发生的事情。

有什么建议？

如果我将模式从InLine更改为PopUp并扩展列，则问题就消失了。但不幸的是，这是不允许的。必须在InLine模式下编辑记录。

我遇到了类似的问题，我想要内联编辑，但也有分层网格。这是他们的代码示例的链接，这激励我采取一定的方向。实现这一切的关键之一是确保在共享视图中定义所需的任何“下拉”类型的内联编辑。
