DataList里面用C#实现自定义分页

PagedDataSource pds=new PagedDataSource();           //设置分页对象的数据源            pds.DataSource=dataSet11.Tables["leaveWords"].DefaultView;           //启用分页功能           pds.AllowPaging=true;           //每页4行           pds.PageSize=4;           //当前页号           int CurrentPageNo;           //页面是否跳转           if(Request.QueryString["Page"]!=null)              //若有跳转请求，将当前页号设置到请求的页号              CurrentPageNo=Convert.ToInt32(Request.QueryString["Page"]);           else              //否则当前页号为1              CurrentPageNo=1;           //设置分页对象的当前页的索引           pds.CurrentPageIndex=CurrentPageNo-1;           LabelCount.Text="共"+pds.PageCount.ToString()+"页";           LabelCurrent.Text="第"+CurrentPageNo.ToString()+"页";           //设置＂上一页＂和＂下一页＂的导航路径           if(!pds.IsFirstPage)              HyperLinkUp.NavigateUrl=Request.CurrentExecutionFilePath+                "?Page="+Convert.ToString(CurrentPageNo-1);           if(!pds.IsLastPage)              HyperLinkDown.NavigateUrl=Request.CurrentExecutionFilePath+                "?Page="+Convert.ToString(CurrentPageNo+1);           //数据绑定到控件DataList1           DataList1.DataSource=pds;           DataList1.DataBind();
