我想从视图中传递一些 selectedValue ： jqgrid 到控制器，我可以用发布数据来做到这一点吗？请帮助我，我有 3 个级联下拉列表，我想用那些 selectedValue 过滤我的网格如何传递参数？

这是行动方法：
public ActionResult LinqGridData(string activite , string sidx, string sord, int page, int rows) {
var context = new FRHEntities();
int pageIndex = Convert.ToInt32(page) - 1;
int pageSize = rows;
int totalRecords = context.productivites.Count();
int totalPages = (int)Math.Ceiling((float)totalRecords / (float)pageSize);
var jsonData = new
{
total = totalPages,
page = page,
records = totalRecords,
rows = frh.productivites.AsEnumerable().Where(n => n.Activité == activite).Select(n => new { id = n.activitéID, cell = new string[] { n.Activité, n.Service.ToString(), n.action, n.vol.ToString(), n.delta_.ToString(), n.tempsmoy_.ToString(), n.tempstot_.ToString() } }).ToArray()
};
return Json(jsonData, JsonRequestBehavior.AllowGet);
}
