The Model-View-Controller (MVC) architectural pattern separates an application into three main components: the model, the view, and the controller. The ASP.NET MVC framework provides an alternative to the ASP.NET Web Forms pattern for creating MVC-based Web applications. The ASP.NET MVC framework is a lightweight, highly testable presentation framework that (as with Web Forms-based applications) is integrated with existing ASP.NET features, such as master pages and membership-based authentication. The MVC framework is defined in the System.Web.Mvc namespace and is a fundamental, supported part of the System.Web namespace. MVC is a standard design pattern that many developers are familiar with. Some types of Web applications will benefit from the MVC framework. Others will continue to use the traditional ASP.NET application pattern that is based on Web Forms and postbacks. Other types of Web applications will combine the two approaches; neither approach excludes the other. MVC架构模 ......
1. 打开新的窗口并传送参数：
传送参数：
response.write("＜script＞window.open('*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"')＜/script＞")
接收参数：
string a = Request.QueryString("id");
string b = Request.QueryString("id1");
2.为按钮添加对话框
Button1.Attributes.Add("onclick","return confirm('确认?')");
button.attributes.add("onclick","if(confirm('are you sure...?')){return true;}else{return false;}")
3.删除表格选定记录
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex];
string deleteCmd = "Delete from Employee where emp_id = " + intEmpID.ToString()
4.删除表格记录警告
private void DataGrid_ItemCreated(Object sender,DataGridItemEventArgs e)
{
switch(e.Item.ItemType)
{
case ListItemType.Item :
case ListItemType.AlternatingItem :
case ListItemType.EditItem:
TableCell myTableCell;
myTableCell = e.Item.Cells[14];
LinkButton myDeleteButton ;
myDeleteButton = (LinkButton)myTableCell.Controls[0];

ASP.NET程序中常用代码汇总
1.自定义异常处理
//自定义异常处理类
using System;
using System.Diagnostics;
namespace MyAppException
{
/// ＜summary＞
/// 从系统异常类ApplicationException继承的应用程序异常处理类。
/// 自动将异常内容记录到Windows NT/2000的应用程序日志
/// ＜/summary＞
public class AppException:System.ApplicationException
{
public AppException()
{
if (ApplicationConfiguration.EventLogEnabled)LogEvent("出现一个未知错误。");
}
public AppException(string message)
{
LogEvent(message);
}
public AppException(string message,Exception innerException)
{
LogEvent(message);
if (innerException != null)
{
LogEvent(innerException.Message);
}
}
//日志记录类
using System;
using System.Configuration;
using System.Diagnostics;
using System.IO;
using System.Text;
using System.Threading;

有人也问了个在线统计的问题，我的见意是这样的：
在Application_Start事件中加入以下代码：
Application.Lock();
Application.["UserCount"]=0;
Application.Unlock();
Session_Start事件中加入以下代码：
Application.Lock();
Application["UserCount']=Int32.Parse(Application["UserCount"].Tostring())+1;
Application.UnLock();
Session_End事件中加入以下代码：
Application.Lock();
Application["UserCount"]=Int32.Parse(Application["UserCount"].Tostring())-1;
Application.UnLock();
在要显示的地方写个函数加入以下代码：
Response.Write(Application["UserCount"].Tostring());
这就OK了 ......
最近写程序一直出问题，以前一个站三几天就轻松搞定，现在一个模块经常搞半天，NND
下午开发酷易化妆品商城(http://www.koyee.net)一个表单提交功能模块，本地任何问题都没有了，传到服务器上本以为没事了，后来一检查所有的验证控件都不起作用了，直接都提交过去了，郁闷，原以为程序被改错了，检查本地还是没任何问题，继续又传了一遍，在服务器上看还是不行；
一下午啥也没干，百度、谷歌的查，技术群的问，朋友的聊，最终总算是解决了，哎，也让自己明白了一个道理，聚沙能成塔 水滴能石穿 铁杵变成针 竹子成牙签；很多事情不是我们不能解决，而是因为我们没有解决之前半途而废，只要努力，一切皆有可能。O(∩_∩)O~
说着说着又跑题了，言归正传，公布解决方法：（asp.net验证控件不起作用的解决办法）
这主要是服务器没有安装相应的 客户端 脚本的原因，在服务器上运行 aspnet_regiis -c(或者aspnet_iisreg -c 不同版本可能不同 ) 命令就可以了，【注：一定要在命令提示下进入C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727类似的目录下执行】
。大家看一下http://www.koyee.net这个站的订单提交那块，就是我做的，现在已经没问题了。
