asp.net2.0中实现无刷新界面的功能
WEB代码如下，主要实现了ICallbackEventHandler接口。比较简单，不多说了。自己看代码
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
public partial class _Default : System.Web.UI.Page ,ICallbackEventHandler
{
string s = "";
protected void Page_Load(object sender, EventArgs e)
{
}
#region ICallbackEventHandler 成员
public string GetCallbackResult()
{
return "服务器的值"+s;
}
public void RaiseCallbackEvent(string eventArgument)
{
s = eventArgument;
}
#endregion
}
