action中定义一个得到结果集的方法

   

public ActionResult GetItemTree(string title, int itemid, int? page)        {            pp = new PagingParam(page ?? 1, VConfig.WebConstConfig.PageSize);            Common.Page.PagedList
     
       res_Item_Resource_R = iResourceService.GetRes_Item_Resource_RByItemId(itemid, pp);            ViewData["res_Item_Resource_R"] = res_Item_Resource_R;            res_Item_Resource_R.AddParameters = new System.Collections.Specialized.NameValueCollection();            res_Item_Resource_R.AddParameters.Add("title", title);            res_Item_Resource_R.AddParameters.Add("itemid", itemid.ToString());            ViewResult vr = new ViewResult            {                ViewData = ViewData,                MasterName = "",            };            return vr;        }
     

    在主页面使用下面jquery代码异步调用上面的action

      

$(function () {        var id = '<%=itemid %>';        $.ajax({            type: "POST",            url: "/Student/GetItemTree",            data: { title: '<%=Model.Name %>', itemid: id, page: 1 },            beforeSend: function (data) { //取回数据前                $("#itemTree").html('数据加载中...');            },            error: function (data) { //发生错误时//                debugger;            },            success: function (data) { //成功返回时                $("#itemTree").html(data);            }        });

   最后在分部视图GetItemTree.ascx中写上你要返回的数据结构即可

   注意一点就是，如果涉及到分页，要用AJAX分页方式

     
              <%=Html.AjaxPager(resItemResourceBefore, "itemTree", "GetItemTree", "Student")%>
