ASP.NET_Page事件的执行顺序

Page 执行中将按照如下顺序激活事件：

<!--<br /> <br /> Code highlighting produced by Actipro CodeHighlighter (freeware)<br /> http://www.CodeHighlighter.com/<br /> <br /> -->Page.PreInit
Page.Init
Page.InitComplite
Page.PreLoad
Page.Load
Page.LoadComplete
Page.PreRender
Page.PreRenderComplete

如果页面从令一个页面继承，如BasePage:System.Web.UI.Page，在BasePage中做了一些扩展，如权限检查，而其他页面从BasePage继承，则BasePage和最终Page的事件激活顺序是：

<!--<br /> <br /> Code highlighting produced by Actipro CodeHighlighter (freeware)<br /> http://www.CodeHighlighter.com/<br /> <br /> -->UI.PreInit
Page.PreInit
UI.Init
Page.Init
UI.InitComplite
Page.InitComplite
UI.PreLoad
Page.PreLoad
UI.Load
Page.Load
UI.LoadComplete
Page.LoadComplete
UI.PreRender
Page.PreRender
UI.PreRenderComplete
Page.PreRenderComplete

如果使用了MasterPage，则MasterPage中的事件和ContentPage中的事件按照下面顺序激活：

<!--<br /> <br /> Code highlighting produced by Actipro CodeHighlighter (freeware)<br /> http://www.CodeHighlighter.com/<br /> <br /> -->ContentPage.PreInit
Master.Init
ContentPage.Init
ContentPage.InitComplite
ContentPage.PreLoad
ContentPage.Load
Master.Load
ContentPage.LoadComplete
ContentPage.PreRender
Master.PreRender
ContentPage.PreRenderComplete

更进一步，如果ContentPage继承BasePage，那么，各事件的执行顺序将变成：

<!--<br /> <br /> Code highlighting produced by Actipro CodeHighlighter (freeware)<br /> http://www.CodeHighlighter.com/<br /> <br /> -->UI.PreInit
ContentPage.PreInit
Master.Init
UI.Init
ContentPage.Init
UI.InitComplite
ContentPage.InitComplite
UI.PreLoad
ContentPage.PreLoad
UI.Load
ContentPage.Load
Master.Load
UI.LoadComplete
ContentPage.LoadComplete
UI.PreRender
ContentPage.PreRender
Master.PreRender
UI.PreRenderComplete
ContentPage.PreRenderComplete
