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：
查看例子
C#版本 <![CDATA[<%@ 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("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" +
Server.MapPath("../aspxWeb.mdb"));
OleDbDataAdapter objCommand=new OleDbDataAdapter("select * from 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 + "?Page=" + Convert.ToString(CurPage-1);
if (!objPds.IsLastPage)
lnkNext.NavigateUrl=Request.CurrentExecutionFilePath+ "?Page=" + Convert.ToString(CurPage+1);
Repeater1.DataSource=objPds;
Repeater1.DataBind();
}
</script>

VB.NET版本 <![CDATA[<%@ Page Language="VB" %>
<%@ import namespace="System.Data" %>
<%@ import namespace="System.Data.OleDb" %>
<script language="VB" runat="server">
Public Sub Page_Load(ByVal src As Object, ByVal e As EventArgs)

Dim ds As DataSet = New DataSet ()
objCommand.Fill(ds)
Dim objPds As PagedDataSource = New PagedDataSource ()
objPds.DataSource = ds.Tables(0).DefaultView
objPds.AllowPaging = True
objPds.PageSize = 5
Dim CurPage As Integer
If Not (Request.QueryString("Page") Is Nothing) Then
CurPage = Convert.ToInt32(Request.QueryString("Page"))
Else
CurPage = 1
End If
objPds.CurrentPageIndex = CurPage - 1
lblCurrentPage.Text = "当前页：" + CurPage.ToString()
If Not objPds.IsFirstPage Then
lnkPrev.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurPage - 1)
End If
If Not objPds.IsLastPage Then
lnkNext.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurPage + 1)
End If
Repeater1.DataSource = objPds
Repeater1.DataBind()
End Sub
