这些属性是否和DataGrid的属性很相似？没错，DataGrid控件就是使用PagedDataSource类来实现数据分页显示的 。下面举个使用PagedDataSource类实现DataList和Repeater控件的分页显示的例子：

public void Page_Load(Object src,EventArgs e) 
{
OleDbConnection objConn=new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=c:test.mdb");
OleDbDataAdapter objCommand=new OleDbDataAdapter("select * from Users",objConn);
DataSet ds=new DataSet();
objCommand.Fill(ds);

//对PagedDataSource 对象的相关属性赋值
PagedDataSource objPds = new PagedDataSource();
objPds.DataSource = ds.Tables[0].DefaultView;
objPds.AllowPaging = true;
objPds.PageSize = 5;
int CurPage;

//当前页面从Page查询参数获取
if (Request.QueryString["Page"] != null)
  CurPage=Convert.ToInt32(Request.QueryString["Page"]);
else
  CurPage=1;

objPds.CurrentPageIndex = CurPage-1; 
lblCurrentPage.Text = "Page: " + 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);

//把PagedDataSource 对象赋给Repeater控件
Repeater1.DataSource=objPds;
Repeater1.DataBind();
}
