嗨，我正在使用 jqgrid 子网格的 trirand 示例（Trirand 示例层次结构 2 级别）。在我的例子中，子网格行为在一个自动生成的javascript函数中。当我将示例"翻译"到我的解决方案（mvc3+razor+实体框架 Cf）时，我在自动生成的子网格函数中收到错误"对象不支持属性或方法"。我确定这是一个简单的错误，但我无法保存它......我希望你能帮助我。
这是我的静态视图：
@{
ViewBag.Title = "Index";
}
<script type="text/javascript">
function showRolesSubGrid(subgrid_id, row_id) {
// the "showSubGrid_OrdersGrid" function is autogenerated and available globally on the page by the second child grid.
// Calling it will place the child grid below the parent expanded row and will call the action specified by the DaraUrl property
// of the child grid, with ID equal to the ID of the parent expanded row
showSubGrid_RolesSubGrid(subgrid_id, row_id);
}
</script>
<div class="bloque">
<div class="ui-widget">
<h2>Index</h2>
<p>
@Html.ActionLink("Create New", "Create")
</p>
@Html.AntiForgeryToken()
<div>
@Html.Trirand().JQGrid(Model.MenuGrid, "MenuGrid")
@Html.Trirand().JQGrid(Model.RolesSubGrid, "RolesSubGrid")
</div>
@Html.Trirand().JQAutoComplete(
new JQAutoComplete
{
DisplayMode = AutoCompleteDisplayMode.ControlEditor,
DataUrl = Url.Action("AutoCompleteName", "MenuItem")
}, "AutoCompleteName")
@Html.Trirand().JQAutoComplete(
new JQAutoComplete
{
DisplayMode = AutoCompleteDisplayMode.ControlEditor,
DataUrl = Url.Action("AutoCompletePadre", "MenuItem")
}, "AutoCompletePadre")
</div>
</div>
这是我的模型网格：

namespace MVC.Models.Grids

{
new JQGridColumn { DataField = "RoleID",
HeaderText = "ID",
PrimaryKey = true,
Width = 50 },
new JQGridColumn { DataField = "RoleName" }
},
Width = Unit.Pixel(650),
Height = Unit.Pixel(350)
};

},

我会欣赏任何解决方向...
我发现了问题，它在我用来显示手风琴菜单的 javascript 集中：
<script src="../../Content/jquery-vertical-accordion-menu/js/jquery.cookie.js" type="text/javascript"></script>
<script src="../../Content/jquery-vertical-accordion-menu/js/jquery.hoverIntent.minified.js" type="text/javascript"></script>
<script src="../../Content/jquery-vertical-accordion-menu/js/jquery.dcjqaccordion.2.7.js" type="text/javascript"></script>
<script src="../../Content/jquery-vertical-accordion-menu/js/jquery.dcjqaccordion.2.7.min.js" type="text/javascript"></script>
从脚本中删除此块，然后子网格显示正常...似乎这个javascript的一部分正在重置jquery函数。
