在ASP.NET MVC中如何讓ASCX使用者控制項具有Action / Controller

一般在MVC頁面中我們使用ASCX使用者控制項我們這樣寫：

<%=Html.Partial("AdminViewLeftMenu") %>

或者這樣寫：

<%Html.RenderPartial("~/Areas/Util/Views/Shared/SelectGroup.ascx"); %> 

上面兩種引用方法的區別：

Html.RenderPartial是直接輸出至當前HttpContext，而Html.Partial是將視圖內容直接產生一個字串並返回。所以在引用的時候不一樣分別為<% Html.RenderPartial("~/Areas/Util/Views/Shared/SelectGroup.ascx"); %>和<%= Html.Partial("~/Areas/Util/Views/Shared/SelectGroup.ascx"); %>。

當需要給ASCX使用者控制項添加action的時候我們就要像下在這樣引用 ：

<%Html.RenderAction("Index", "SectionGroup");%>

Action如下：

using System;  using System.Collections.Generic;  using System.Linq;  using System.Web;  using System.Web.Mvc;   namespace EducationManage.Areas.Util.Controllers  {      using Utility.Json;      using EducationManage.Areas.Util.Models;      public class SectionGroupController : Controller      {          //          // GET: /Util/SectionGroup/          SelectgroupEntities selectgroupEntities = new SelectgroupEntities();          public ActionResult Index()          {              List<SG_Admission_Batchs> admissionBatchList = selectgroupEntities.admission_batchs.ToList();              SelectList admissionBatch = new SelectList(admissionBatchList, "admission_batch_id", "name", "");              ViewData.Add("admissionBatch", admissionBatch);               List<SG_Education_Levels> educationLevelList = selectgroupEntities.education_levels.ToList();              SelectList educationLevel = new SelectList(educationLevelList, "education_id", "name", "");              ViewData.Add("educationLevel", educationLevel);               List<SG_Professional> professionalList = selectgroupEntities.professional.ToList();              SelectList professional = new SelectList(professionalList, "prefessional_code", "name", "");              ViewData.Add("professional", professional);              return PartialView("~/Areas/Util/Views/Shared/SectionGroup.ascx");          }       }  }
