Repeater和DataList控件提供了一个快速、灵活的表现数据的方式，但是，它们没有内建的分页功能；DataGrid控件提供了内建的分页功能，但它的结构比较复杂。下面就用PagedDataSource类实现Repeater和DataList的分页。 PagedDataSource封装了DataGrid的分页属性，我们可以象DataGrid那样进行分页。代码如下：
以下为引用的内容：
<%@ Page Language="C#" %>
<%@ import namespace="System.Data" %>
<%@ import namespace="System.Data.OleDb" %>
<script language="C#" runat="server">
public void Page_Load(Object src,EventArgs e) {
OleDbConnection objConn=new OleDbConnection("<br>
Provider=Microsoft.Jet.OLEDB.4.0;
Data Source=" + Server.MapPath("../aspxWeb.mdb"));
OleDbDataAdapter objCommand=new OleDbDataAdapter("select * from<br>
Document",objConn); DataSet ds=new DataSet();objCommand.Fill(ds); PagedDataSource objPds = new PagedDataSource();
objPds.DataSource = ds.Tables[0].DefaultView;
objPds.AllowPaging = true;
objPds.PageSize = 5;
int CurPage;
if (Request.QueryString["Page"] != null)
CurPage=Convert.ToInt32(Request.QueryString["Page"]);
else
CurPage=1; objPds.CurrentPageIndex = CurPage-1;
lblCurrentPage.Text = "当前页：" + CurPage.ToString(); if (!objPds.IsFirstPage)
lnkPrev.NavigateUrl=Request.CurrentExecutionFilePath + <br>
"?Page=" + Convert.ToString(CurPage-1); if (!objPds.IsLastPage)
lnkNext.NavigateUrl=Request.CurrentExecutionFilePath+ "<br>
?Page=" + Convert.ToString(CurPage+1); Repeater1.DataSource=objPds;
Repeater1.DataBind();
}
</script>
