利用menu实现后台管理用户界面

asp.net menu控件，在普通页面只会执行一次MenuItemClick事件。如果用母版页，把menu放在页面左边，内容页
放在右面，很容易解决menu只响应一次的问题。
先建立母版页site1.master
前台代码：
<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site1.master.cs" Inherits="WebApplication1.Site1" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
<asp:ContentPlaceHolder ID="head" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<form id="form1" runat="server">
<div style="margin-top:20px;background-color:lightblue;">
<asp:Label ID="Label1" runat="server" Width="90%" Text=" Manage user "></asp:Label>
</div>
<div style="float:left;margin-left:100px;margin-top:50px">
<asp:Menu ID="Menu1" runat="server" StaticDisplayLevels="2" OnMenuItemClick="Menu1_MenuItemClick" >
<Items >
<asp:MenuItem Text="User Manage" Value="manage" Selectable="False">
<asp:MenuItem Text="Add user" Value="add"></asp:MenuItem>
<asp:MenuItem Text="Modify password" Value="modify"></asp:MenuItem>
<asp:MenuItem Text="Permission" Value="mpermission"></asp:MenuItem>
<asp:MenuItem Text="User void" Value="uservoid"></asp:MenuItem>
</asp:MenuItem>
</Items>
</asp:Menu>
</div>
<div style="float:right;margin-right:700px;margin-top:100px">
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</div>
</form>
</body>
</html>
后台c#代码
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace WebApplication1
{
public partial class Site1 : System.Web.UI.MasterPage
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Menu1_MenuItemClick(object sender, MenuEventArgs e)
{
if (Menu1.SelectedValue == "add")
{
Response.Redirect("Default.aspx?rowdis=" + "add");
return;
}
else
{
if (Menu1.SelectedValue == "modify")
{
Response.Redirect("Default.aspx?rowdis=" + "modify");
return;
}
else
{
if (Menu1.SelectedValue == "uservoid")
{
Response.Redirect("Default.aspx?rowdis=" + "uservoid");
return;
}
else
{
if (Menu1.SelectedValue == "mpermission")
{
Response.Redirect("Default.aspx?rowdis=" + "mpermission");
return;
}
}
}
}
}
}
}默认一个主页，就是menu没有点击的时候显示的页面。比如是webform3.aspx,不执行任何代码
<%@ Page Title="主页" Language="C#" AutoEventWireup="true" MasterPageFile="~/Site1.Master" CodeBehind="WebForm3.aspx.cs" Inherits="WebApplication1.WebForm3" %>
<asp:Content runat="server" ID="BodyContent" ContentPlaceHolderID="ContentPlaceHolder1">
</asp:Content>
下面是真正的内容页default.aspx，前台代码：
<%@ Page Title="主页" Language="C#" AutoEventWireup="true" MasterPageFile="~/Site1.Master" CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" %>
<asp:Content runat="server" ID="BodyContent" ContentPlaceHolderID="ContentPlaceHolder1">
<script type="text/JavaScript">
function checkForm() {
var _uid = document.getElementById("<%=username.ClientID %>").value;
var _upwd = document.getElementById("<%=password.ClientID %>").value;
var _upwdSure = document.getElementById("<%=passwordconfirm.ClientID %>").value;
if (_uid == "") {
alert("username not empty!");
return false;
}
if (_upwd != _upwdSure) {
alert("twice passwords are not match ");
return false;
}
var reg = /^[a-zA-Z0-9]{6,8}$/g;
if (!reg.test(_upwd)) {
alert("Password length must be 6 -8 characters, can only be English words, numbers, for example: snsn2016, etc.");
return false;
}
var reguser = /^[a-zA-Z]/;
if (!reguser.test(_uid)) {
alert("username can only be English words for example: snsn, etc.");
return false;
}
}
</script>
<div >

namespace WebApplication1
{
public partial class _Default : Page

}
}
private void inittextbox()
{
username.Text = "";
password.Text = "";

后面在加一个抽象类，用来做页面传参的加密工作code.cs：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Security.Cryptography;
using System.IO;
using System.Text;
namespace WebApplication1
{
public abstract class code
{
public static string key = "20161030", iv = "01234567";
public static string Encrypt(string sourceString)
{
try
{
byte[] btKey = Encoding.UTF8.GetBytes(key);
byte[] btIV = Encoding.UTF8.GetBytes(iv);
DESCryptoServiceProvider des = new DESCryptoServiceProvider();
using (MemoryStream ms = new MemoryStream())
{
byte[] inData = Encoding.UTF8.GetBytes(sourceString);
try
{
using (CryptoStream cs = new CryptoStream(ms, des.CreateEncryptor(btKey, btIV), CryptoStreamMode.Write))
{
cs.Write(inData, 0, inData.Length);
cs.FlushFinalBlock();
}
return Convert.ToBase64String(ms.ToArray());
}
catch
{
return sourceString;
}
}
}
catch { }
return "DES error";
}
public static string Decrypt(string encryptedString)
{
byte[] btKey = Encoding.UTF8.GetBytes(key);
byte[] btIV = Encoding.UTF8.GetBytes(iv);
DESCryptoServiceProvider des = new DESCryptoServiceProvider();
using (MemoryStream ms = new MemoryStream())
{
byte[] inData = Convert.FromBase64String(encryptedString);
try
{
using (CryptoStream cs = new CryptoStream(ms, des.CreateDecryptor(btKey, btIV), CryptoStreamMode.Write))
{
cs.Write(inData, 0, inData.Length);
cs.FlushFinalBlock();
}
return Encoding.UTF8.GetString(ms.ToArray());
}
catch
{
return encryptedString;
}
}
}
}
}
放在右面，很容易解决menu只响应一次的问题。
