1、正则表达式：验证数据格式的准确性。

用正则表达式判断手机号格式是否正确：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
             
     
    
      
    
               
       
           
      
    
     

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;public partial class _Default : System.Web.UI.Page{    protected void Page_Load(object sender, EventArgs e)    {    }}

2、用加减按钮增加减少数量

 

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>
             
     
    
      
        
               
               
               
               
           
      
    
     

 

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;public partial class Default2 : System.Web.UI.Page{    protected void Page_Load(object sender, EventArgs e)    {        Button1.Click += Button1_Click;    }    void Button1_Click(object sender, EventArgs e)    {        Label1.Text = TextBox1.Text;    }}

3、用checkbox实现全选

 

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default3.aspx.cs" Inherits="Default3" %>
             
     
    
      
        
                   
                          
        
       
       
                    
         
                          
  全选
                          
编号
                           
姓名
                           
密码
                           
昵称
                           
性别
                          
生日
                          
民族
                     
                                     
                                
 "/>
                          
<%#Eval("ids") %>
                           
<%#Eval("username") %>
                           
<%#Eval("password") %>
                           
<%#Eval("nickname") %>
                           
<%#Eval("sex") %>
                          
<%#Eval("birthday") %>
                          
<%#Eval("nation") %>
                     
                                                   
       
         
                   
           
      
    
     

 

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;public partial class Default3 : System.Web.UI.Page{    protected void Page_Load(object sender, EventArgs e)    {        if(!IsPostBack)        {            Repeater1.DataSource = new user1data().selectall();            Repeater1.DataBind();        }        Button1.Click += Button1_Click;    }    void Button1_Click(object sender, EventArgs e)    {        Label1.Text = Request["ck"];    }}

 

 

using System;using System.Collections.Generic;using System.Linq;using System.Web;/// 
/// user1data 的摘要说明/// 
public class user1data{    DataClassesDataContext con = new DataClassesDataContext();    public user1data()    {    }    public List
     
       selectall()     {        return con.user1.ToList();    }}
