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！
