Asp.net mvc 3 jqSubGrid未加载数据

我知道很多人都问过同样的问题。我尝试过所有其他建议，但都没有成功。我确信这是我忽略了的事情，我希望有第二双眼睛来帮助我。提前谢谢

我的问题是，主网格负载可以找到。问题出在子电网上

<script type="text/javascript">
    jQuery(document).ready(function () {
        jQuery("#PositionsGrid").jqGrid({
            url: '/Position/GetPositions?projectid=@Model.ID',

您还需要传递到jqgrid：

            page = numberOfPages
            records = totalRecords,

我个人使用的是：

        var jsonData = new
        {
            total = (totalRecords + rows - 1) / rows,
            page = page,
            records = totalRecords,
            rows = (
                from item in pagedQuery                  
                select new
                {
                    cell = new string[] {       
                       item.value1,
                       item.value2, ....
                    }
                }).ToArray()

        };
        return Json(jsonData, JsonRequestBehavior.AllowGet);

原来我没有使用JsonRequestBehavior.AllowGet，这就是我出现问题的原因！！

        var jsonData = new
        {
            total = (totalRecords + rows - 1) / rows,
            page = page,
            records = totalRecords,
            rows = (
                from item in pagedQuery                  
                select new
                {
                    cell = new string[] {       
                       item.value1,
                       item.value2, ....
                    }
                }).ToArray()

        };
        return Json(jsonData, JsonRequestBehavior.AllowGet);
