学习atlas有一段时间了，培训讲座也听了些，但是具体没有使用过，准备写一个atlas学习系列，从简单的开始，逐一学习总结一下atlas的 用法，本文介绍如何使用atlas来支持简单的无刷新效果。主要目的是体会一下atlas的强大功能。用的也是atlas官方demo，大家可以在它网站 上下载，自己只是简单重复的实践了一把。

1.atlas:ScriptManager :我揣摩加上这个标签，页面就注册了一下调用服务器端ajax代码的js，从原文件中也可以看出，在相应位置，产生如下代码为：
2.atlas:UpdateProgress , ProgressTemplate
生成一个div标签，以后更改div的visiable。
3。atlas:UpdatePanel
a. ContentTemplate 我估计加上这种标签，相当于将该标签下的控件变成ajax控件，即交互都通过xmlhttp来实现。
b.Triggers 这个标签用来处理页面事件。分为两类
1）atlas:ControlValueTrigger : 控件值触发，比如设置控件为DropDownList1,源代码中就在DropDownList1控件生成的Select表单加上οnchange= "javascript:setTimeout('__doPostBack(\'ctl00$ContentPlaceHolder1$DropDownList1\',\'\')', 0)"如下语句。这样就可以触发该控件的事件了。
2）atlas:ControlEventTrigger：估计是截取控件事件，将js方法写到指定方法中。
先写道这里，有空写下一篇。
