AspNetPager + GridView + ASP.NET AJAX 分頁無重新整理實現

在網上看到這篇文章《AspNetPager + GridView + ASP.NET AJAX 分頁無重新整理實現 》 感覺收穫很大， 這裡推薦給大家，

public partial class HYZXLIST : System.Web.UI.Page{    protected void Page_Load(object sender, EventArgs e)    {        if (!IsPostBack)        {            GetData();        }    }      private void GetData()    {        Info i = new Info();        int classid = 1;        if (!string.IsNullOrEmpty(Request.QueryString["classid"]))        {            classid = int.Parse(Request.QueryString["classid"].ToString());        }        int pageindex = 1;        //if (Request["page"] != null)        //{        //    pageindex = Convert.ToInt32(Request["page"]);        //}        if (AspNetPager1.CurrentPageIndex < 1)        {            pageindex = 1;        }        else        {            pageindex = AspNetPager1.CurrentPageIndex;        }        int pagenum = AspNetPager1.PageSize;        int recordcount;        string classname;        ListView1.DataSource = i.GetInfoByClassID(pageindex, pagenum, out recordcount, classid, out classname);        ListView1.DataBind();        titleleft.InnerText = classname;        titleright.InnerHtml = "你現在的位置>>" + classname;        AspNetPager1.RecordCount = recordcount;    }    protected void AspNetPager1_PageChanging(object src, Wuqi.Webdiyer.PageChangingEventArgs e)    {        AspNetPager1.CurrentPageIndex = e.NewPageIndex;        GetData();    }    protected void AspNetPager1_PageChanged(object sender, EventArgs e)    {    }}

可以看到這裡用的是page_changing事件；

剛開始使用的pagechanged事件 老是提示莫名奇怪的錯誤，或者乾脆沒有翻頁效果；
