Question

我一直在＆＃34;没有要显示的项目＆＃34;在我的孩子网格。我有2个视图模型，Master和Name。 Master可以绑定多个Name。当我执行页面时，它会按预期显示主信息。但它的子名称没有显示任何项目，但是当我在JSON上断点时它包含2个返回的名称。

的 Index.cshtml

@(
 Html.Kendo().Grid(Model).Name("MainGrid")
    .Columns(col =>
    {
        col.Bound(m => m.ListingId).Width(100);
        col.Bound(m => m.Gender).Width(100);

    })
    .ClientDetailTemplateId("NameGridTemplate")
    .Reorderable(reorder => reorder.Columns(true))
    .Sortable()
    .Scrollable()
    .Filterable()
    .Groupable()
    .Pageable()
    .DataSource(ds => ds
        .Ajax()
        .Model(m => m.Id(i => i.ListingId))
        .Read(read => read.Action("HierarchyBinding_Master", "Main"))  
    )
    .Events(events => events.DataBound("dataBound"))

)

<script id="NameGridTemplate" type="text/kendo-tmpl">
    @(Html.Kendo().Grid<NameViewModel>()
            .Name("grid_#=ListingId#") // template expression, to be evaluated in the master context
            .Columns(columns =>
            {
                columns.Bound(o => o.PersonName).Width(110);
                columns.Bound(o => o.Type).Width(110);

            })
            .DataSource(dataSource => dataSource
                .Ajax()
                .PageSize(10)
                .Read(read => read.Action("HierarchyBinding_Name", "Main", new { listingId = "#=ListingId#" }))

            )
            .Pageable()
            .Sortable()
            .ToClientTemplate()
    )
</script>

<script>
    function dataBound() {
        this.expandRow(this.tbody.find("tr.k-master-row").first());
    }
</script>

请试试这个

public ActionResult HierarchyBinding_Name(int listingId, [DataSourceRequest] DataSourceRequest request)
{
    List<Name> nameList = null;
    nameList = db.Names.ToList();

    return  Json(nameList
        .Where(name => name.ListingId == listingId)
        .ToDataSourceResult(request));
}

删除Jsonrequestbehaviour.Allowget。

我认为它会起作用。我没有看到你的剃刀代码有什么问题
