發布時間：2023/12/10 编程问答 29 豆豆

生活随笔收集整理的這篇文章主要介紹了我的分页代码小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

??private void Page_Load(object sender, System.EventArgs e)
??{
???// 在此處放置用戶代碼以初始化頁面
???if(!this.IsPostBack)
???{
????string PageIndex=Request.QueryString["PageIndex"];
????if(PageIndex==null||PageIndex.Length==0)//這種方法判斷快一些
????{
?????this.BindData(this.Repeater1,1,5);
?????this.Label1.Text=this.ViewPage(1,5);
????}
????else
????{
?????this.BindData(this.Repeater1,Convert.ToInt32(PageIndex),5);
?????this.Label1.Text=this.ViewPage(Convert.ToInt32(PageIndex),5);
????}
???}
