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

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 = "width:300px;" })%>

生成结果:

11.TextArea

<%=Html.TextArea("input5", Model.CategoryName, 3, 9,null)%>

<%=Html.TextAreaFor(a => a.CategoryName, 3, 3, null)%>

生成结果:

12.CheckBox

<%=Html.CheckBox("chk1",true) %>

<%=Html.CheckBox("chk1", new { @class="checkBox"}) %>

<%=Html.CheckBoxFor(a =>a.IsVaild, new { @class = "checkBox" })%>

生成结果:

13.ListBox

<%=Html.ListBox("lstBox1",(SelectList)ViewData["Categories"])%>

<%=Html.ListBoxFor(a => a.CategoryName, (SelectList)ViewData["Categories"])%>

生成结果:

14.DropDownList

<%= Html.DropDownList("ddl1", (SelectList)ViewData["Categories"], "--Select One--")%>

<%=Html.DropDownListFor(a => a.CategoryName, (SelectList)ViewData["Categories"], "--Select One--", new { @class = "dropdownlist" })%>

生成结果:

15.Partial 视图模板

webform里叫自定义控件。功能都是为了复用。但使用上自定义控件真的很难用好。

<% Html.RenderPartial("DinnerForm"); %> 看清楚了没有等号的。

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) %>



<% } %>
