无法加载网格中的分层数据。 0 items

我一直在我的子网格中显示“No items to display”。我有2个视图模型，主人和名字。主人可以绑定多个姓名。当我执行该页面时，它会按预期显示主信息。但是它的子项名称没有显示任何项目，尽管当我在JSON上断点时它包含它返回的2个名称。无法加载网格中的分层数据。 0 items

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)); 
}

取出Jsonrequestbehaviour.Allowget。

我认为它会工作。我没有看到你的剃刀代码有任何问题
