谁能给我个datalist分页的简单例子

[mypigcasey]

初学asp.net请大家多多帮忙!

假设你的datalist id 为:DataList1,数据源为DataTable并名为dtlist,那么事先在aspx添加两个HyperLink id分别为:HyperLink1 HyperLink2和一个Label id为Label1
那么可以这样:
//创建分页类
PagedDataSource Fpage=new PagedDataSource();
//设置数据源
Fpage.DataSource = dtlist.DefaultView;
//允许分页
Fpage.AllowPaging=true;
//设置每页显示项数
Fpage.PageSize=6;
//定义变量用来保存当前索引
int CurPage;
//判断是否具有页面跳转的请求
if(Request.QueryString["Page"]!=null)
CurPage=Convert.ToInt32(Request.QueryString["Page"]);
else
CurPage=1;
//设置当前页的索引
Fpage.CurrentPageIndex=CurPage-1;
//显示当前页是第几页
this.Label1.Text="当前页:第"+CurPage.ToString()+"页";
//如果当前页不是首页的话
if(!Fpage.IsFirstPage)
//定义"上一页"的超级链接
this.HyperLink1.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurPage - 1);
//如果不是最后一页的话
if(!Fpage.IsLastPage)
//定义"下一页"的超级链接
this.HyperLink2.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurPage + 1);
//进行数据绑定
this.DataList1.DataSource = Fpage;
this.DataList1.DataBind();
就可以了.

好乱哦..

[mypigcasey]

public void page_Click(Object sender, CommandEventArgs e)
{
CurrentPage = (int)ViewState["PageIndex"];
PageCount = (int)ViewState["PageCount"];
string cmd = e.CommandName;
switch (cmd)
{
case "next":
if (CurrentPage < (CurrentPage - 1))
CurrentPage++;
break;
case "prev":
if (CurrentPage > 0)
CurrentPage--;
break;
}
ViewState["PageIndex"] = CurrentPage;
BindDataList();
}

CurrentPage = (int)ViewState["PageIndex"];//请问这两句是什么意思????
PageCount = (int)ViewState["PageCount"];//请问这两句是什么意思????

}
