1、正巧今天遇到一个获取动态生成table中的一个动态生成的TextBox的值的时候总是findcontrol不到。后来经过我们的徐总，瞬间解决，但是我觉得对于一个页面的声明周期，我了解的还是很少，今天希望能通过这篇文章，再次了解一遍。3.1页面生命周期3.1.1独立页面生命周期事件顺序publicpartialclass_Default:System.Web.UI.Page{protectedvoidPage_PreInit(objectsender,EventArgse){Response.Write("Page_P

");inti=0;i++;//这行代码是用来设置断点的，这里不能用Response.Write}protectedvoidButton1_Click(objectsender,EventArgse){Response.Write("Button事件触发！
");}}输出结果：Page_PreInitPage_InitPage
