ASP.NET中用编程的方法控制UpdatePanel的更新
UpdatePanel可以用来创建丰富的局部更新Web应用程序，它是ASP.NET 2.0 AJAX Extensions中很重要的一个控件。对于UpdatePanel，我们也可以使用编程的方法来控制它的更新，可以通过ScriptManager的RegisterAsyncPostBackControl()方法注册一个异步提交的控件，并且调用UpdatePanel的Update()方法来让它更新。再次用我在前面的文章中用到的一个无聊的时间更新例子来看一下，有时候我觉得例子过于复杂更加不好说明白所要讲的内容，如下代码所示，注意Button1并不包含在UpdatePanel中：
<%@PageLanguage="C#"AutoEventWireup="true"CodeFile="Default
.aspx.cs"Inherits="_Default"%><scriptrunatscriptrunat="server">
voidButton1_Click(objectsender,EventArgse)
{
this.Label2.Text=DateTime.Now.ToString();
}
script>
