MVC2 中某些控件的用法

10.TextBox , Hidden %=Html.TextBox(input1) % %=Html.TextBox(input2,Model.CategoryName,new{ @style = width:300px; }) % %=Html.TextBox(input3, ViewData[Name],new{ @style = width:300px; }) % %=Html.TextBoxFor(a = a.CategoryName, new { @style

16 mvc中的模糊查询和精确查询： 

    var talk = dbTalk.talk.Where(m => m.name.IndexOf(keyWord)>=0);//模糊查询

  dbTalk.talk.Where(m => m.name.Equals(keyWord) == true);//精确查询

应用：

在控制器中的Action：

      public ActionResult search()
        {
           string keyWord = Request.Form["keyWord"];
           var talk = dbTalk.talk.Where(m => m.name.IndexOf(keyWord)>=0);//dbTalk.talk.Where(m => m.name.Equals(keyWord) == true);//
           if (talk == null)
           { ViewData["error"] = "未找到相关信息！"; }
           else
           { ViewData["error"] = "Yes！";}
           ViewData.Model = talk; //视图页面数据
           return View();
        }

view中代码：

  <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %>
<%@ Import Namespace="MvcApplication1.Models" %>//引入models

<% foreach (talk item in (IEnumerable)ViewData.Model)//转换为你想要的类型（ViewData.Model为控制器中传过来的数据）
       { %>
   
       
           
                <%= Html.ActionLink("Edit", "Edit", new { id=item.id }) %> |
                <%= Html.ActionLink("Details", "Details", new { id=item.id })%> |
                <%= Html.ActionLink("Delete", "Delete", new { id=item.id })%>
           
           
                <%= Html.Encode(item.id) %>
           
           
                <%= Html.Encode(item.name) %>
           
           
                <%= Html.Encode(item.text) %>
           
           
                <%= Html.Encode(item.time) %>
           
       
   
    <% } %>
