ASP.NET 生命周期
对于Asp.net页面层开发无论是写页面还是写控件，我觉得都可以用一句话描述:"Do the right thing at the right time in the right place."
本文通过记录页面事件的触发顺序看请求的处理流程，从中可以看出ASP.NET 的生命周期
创建一个网站，在页面上添加一个Label和一个Button，在Default.aspx.cs中修改代码如下：
using System;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
public partial class _Default : System.Web.UI.Page
{
protected void Page_PreInit(object sender, EventArgs e)
{
Response.Write("Page_PreInit<br/>");
}
protected void Page_Init(object sender, EventArgs e)
{
Response.Write("Page_Init<br/>");
}
protected void Page_InitComplete(object sender, EventArgs e)
{
Response.Write("Page_InitComplete<br/>");
}
protected void Page_PreLoad(object sender, EventArgs e)
{
Response.Write("Page_PreLoad<br/>");
}
protected void Page_Load(object sender, EventArgs e)
{
Response.Write("Page_Load<br/>");
}
protected void Page_LoadComplete(object sender, EventArgs e)
{
Response.Write("Page_LoadComplete<br/>");
}
protected void Page_PreRender(object sender, EventArgs e)
{
Response.Write("Page_PreRender<br/>");
}
protected void Page_PreRenderComplete(object sender, EventArgs e)
{
Response.Write("Page_PreRenderComplete<br/>");
}
protected void Page_SaveStateComplete(object sender, EventArgs e)
{
Response.Write("Page_SaveStateComplete<br/>");
}
protected void Page_Unload(object sender, EventArgs e)
{
int i = 0;
i++; ////这行代码是用来设置断点的
}

在gridview中
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">
<SelectedRowStyle BackColor="#CE5D5A" Font-Bold="True" ForeColor="White" />
<asp:TemplateField HeaderText="Remove">
&nbs ......
1.Application：用于保存所有用户共用的数据信息。 在Asp.Net中类似的配置数据最好保存在Web.config文件中。如果使用Application对象，一个需要考虑的问题是任何写操作都要在 Application_OnStart事件（global.asax）中完成。尽管使用Application.Lock和 Application.Unlock方法来避免写操作的同步，但是它串行化了Applicat ......
