AjaxPro实现无刷新模仿MSN提示消息功能
好友在一家公司做网上销售的网站，在后台管理这块，想要实现新订单时时维护的功能，做一个类似msn信息提示的对话框，可以针对数据库中新的订单做一个信息提示框。用AjaxPro.2.dll可以实现该功能，具体操作如下:
1.引用AjaxPro.2.dll
2.WebConfig中添加配置
Code
<system.web> <httpHandlers> <add verb="POST,GET" path="ajaxpro/*.ashx" type="AjaxPro.AjaxHandlerFactory, AjaxPro.2"/> </httpHandlers> </system.web>
3.shyMSN页面的后台服务器代码
Codeusing System;
using System.Data;
using System.Configuration;
using System.Collections;
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;
using System.Diagnostics;
using System.Data.SqlClient;
public partial class shyMSN : System.Web.UI.Page
{
Random rd = new Random();
public string caption
{
get { return "后台订单系统提示信息:"; }
}
public string title
{
get { return "你有"; }
}
public string url
{
get { return "Order.aspx"; }//转向订单操作页面
}
protected void Page_Load(object sender, EventArgs e)
{
#region 注册无刷新
AjaxPro.Utility.RegisterTypeForAjax(typeof(shyMSN));//shyMSN为当前页面的类名
#endregion
}
#region "用来检索数据库新消息的记录数"
[AjaxPro.AjaxMethod]
public string getxx()
{
int news = rd.Next(1, 10);
return news.ToString(); //随机数代表新信息的个数 可以改成和数据库的交互（查询新订单的个数)
}
#endregion
