序
 一、用户
 二、用户组
 三、栏目
3.1添加栏目
3.2浏览栏目 
3.3更新栏目 

上次在树形列表里面点击栏目名称后跳转到详细信息页面~/Category/ManageDetails/id。在详细页面里点修改，来完成栏目资料修改。

 先打开【CategoryController】添加[ManageDetails(int id)]action 

/// <summary>
 /// 栏目详细资料
 /// </summary>
 /// <param name="id"></param>
 /// <returns></returns>
 public ActionResult ManageDetails(int id)
 {
 categoryRsy = new CategoryRepository();
 var _node = categoryRsy.Find(id);
 if (_node == null)
 {
 Error _e = new Error { Title = "栏目不存在", Details = "栏目不存在", Cause = Server.UrlEncode("<li>栏目已经删除</li>"), Solution = Server.UrlEncode("<li>返回<a href='" + Url.Action("Manage", "Cayegory") + "'>栏目栏目管理</a></li>") };
 return RedirectToAction("ManageError", "Prompt", _e);
 }
 ModuleRepository _moduleRsy = new ModuleRepository();
 var _modules = _moduleRsy.List(true);
 List<SelectListItem> _slimodule = new List<SelectListItem>(_modules.Count());
 foreach (Module _module in _modules)
 {
 if (_node.Model == _module.Model) _slimodule.Add(new SelectListItem { Text = _module.Name, Value = _module.Model, Selected = true });
 else _slimodule.Add(new SelectListItem { Text = _module.Name, Value = _module.Model });
 }
 ViewData.Add("Model", _slimodule);
 var _type = TypeSelectList;
 _type.SingleOrDefault(t => t.Value == _node.Type.ToString()).Selected = true;
 ViewData.Add("Type", _type);
 return View(_node);
 }

代码先是看栏目是否存在，不存在跳转到错误页面，后面是添加"Model“和“Type”的ViewData
右键添加强类型视图ManageDetails.cshtml,内容基本与ManageAdd.cshtml类似 

@model Ninesky.Models.Category

@{
 ViewBag.Title = "栏目信息";
 Layout = "~/Views/Layout/_Manage.cshtml";
}

<div class="workspace">
 <div class="inside">
 <div class="notebar">
 <img " src="~/Skins/Default/Manage/Images/Category.gif" />栏目信息

 @using (Html.BeginForm("ManageUpdate","Category"))
 {
 @Html.ValidationSummary(true)

 }
 }

@section Scripts {

 @Scripts.Render("~/bundles/EasyUi")
 @Scripts.Render("~/bundles/jqueryval")
}

注意的是 @using (Html.BeginForm("ManageUpdate","Category"))这句；表示点修改按钮的后是向ManageUpdate提交数据。下面开始做这个action 

在【CategoryController】里添加httppost方式的[ManageUpdate]action 

/// <summary>
 /// 修改栏目信息
 /// </summary>
 /// <param name="category"></param>
 /// <returns></returns>
 public ActionResult ManageUpdate(Category category)
 {
 switch (category.Type)
 {
 case 0:
 category.Navigation = "";
 break;
 case 1:
 category.Model = "";
 category.ContentView = "";
 category.Navigation = "";
 break;
 case 2:
 category.Model = "";
 category.CategoryView = "";
 category.ContentView = "";
 break;
 }
 categoryRsy = new CategoryRepository();
 if (categoryRsy.Update(category))
 {
 Notice _n = new Notice { Title = "修改栏目成功", Details = "修改栏目成功！", DwellTime = 5, NavigationName = "栏目详细信息", NavigationUrl = Url.Action("ManageDetails", "Category", new { id = category.CategoryId }) };
 return RedirectToAction("ManageNotice", "Prompt", _n);
 }
 else
 {
 Error _e = new Error { Title = "修改栏目失败", Details = "在修改栏目信息时，未能保存到数据库", Cause = "系统错误", Solution = Server.UrlEncode("<li>返回<a href='" + Url.Action("ManageDetails", "Category", new { id = category.CategoryId }) + "'>栏目详细资料</a>页面，修改信息后重新操作</li><li>联系网站管理员</li>") };
 return RedirectToAction("ManageError", "Prompt", _e);
 }
 }

很简单，首先是判断栏目类型，根据栏目类型清除无关数据，然后将修改保存到数据库。
试一下将“测试栏目”改成“公司简介” 

保存成功！
