C# ASP.NET MVC HtmlHelper用法大全 (转)

public static string TextBox( this HtmlHelper htmlHelper, string name, Object value, IDictionary < string , Object > htmlAttributes )
public static string TextBox( this HtmlHelper htmlHelper, string name, Object value, Object htmlAttributes )

<% = Html.ActionLink( " 这是一个连接 " , " Index " , " Home " ) %>
带有QueryString的写法
<% = Html.ActionLink( " 这是一个连接 " , " Index " , " Home " , new { page = 1 }, null ) %>
<% = Html.ActionLink( " 这是一个连接 " , " Index " , new { page = 1 }) %>
有其它Html属性的写法
<% = Html.ActionLink( " 这是一个连接 " , " Index " , " Home " , new { id = " link1 " }) %>
<% = Html.ActionLink( " 这是一个连接 " , " Index " , null , new { id = " link1 " }) %>
QueryString与Html属性同时存在
<% = Html.ActionLink( " 这是一个连接 " , " Index " , " Home " , new { page = 1 }, new { id = " link1 " }) %>
<% = Html.ActionLink( " 这是一个连接 " , " Index " , new { page = 1 }, new { id = " link1 " }) %>
生成结果为：
< a href ="/" > 这是一个连接 </ a >
带有QueryString的写法
< a href ="/?page=1" > 这是一个连接 </ a >
< a href ="/?page=1" > 这是一个连接 </ a >
有其它Html属性的写法
< a href ="/?Length=4" id ="link1" > 这是一个连接 </ a >
< a href ="/" id ="link1" > 这是一个连接 </ a >
QueryString与Html属性同时存在
< a href ="/?page=1" id ="link1" > 这是一个连接 </ a >
< a href ="/?page=1" id ="link1" > 这是一个连接 </ a >

跟ActionLink在功能上一样。
<% = Html.RouteLink( " 关于 " , " about " , new { }) %>
带QueryString
<% = Html.RouteLink( " 关于 " , " about " , new { page = 1 }) %>
<% = Html.RouteLink( " 关于 " , " about " , new { page = 1 }, new { id = " link1 " }) %>
生成结果：
< a href ="/about" > 关于 </ a >
< a href ="/about?page=1" > 关于 </ a >
< a href ="/about?page=1" id ="link1" > 关于 </ a >

<% using(Html.BeginForm( " index " , " home " ,FormMethod.Post)){ %>
<% } %>
<% Html.BeginForm( " index " , " home " , FormMethod.Post); // 注意这里没有 = 输出 %>
<% Html.EndForm(); %>
生成结果：
< form action ="/home/index" method ="post" ></ form >

<% = 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; " }) %>

< input id ="input2" name ="input2" style ="width:300px;" type ="text" value ="Beverages" />
< input id ="input3" name ="input3" style ="width:300px;" type ="text" value ="" />

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

< textarea cols ="3" id ="CategoryName" name ="CategoryName" rows ="3" > Beverages </ textarea >

<% = Html.CheckBox( " chk1 " , true ) %>
<% = Html.CheckBox( " chk1 " , new { @class = " checkBox " }) %>
<% = Html.CheckBoxFor(a => a.IsVaild, new { @class = " checkBox " }) %>
生成结果：
< input checked ="checked" id ="chk1" name ="chk1" type ="checkbox" value ="true" />
< input name ="chk1" type ="hidden" value ="false" />
< input class ="checkBox" id ="chk1" name ="chk1" type ="checkbox" value ="true" />

< input checked ="checked" class ="checkBox" id ="IsVaild" name ="IsVaild" type ="checkbox" value ="true" />

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

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 " ); %>
