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:

<%@ Page Language=”C#” %>

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);
\n
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;
\n
objPds.CurrentPageIndex = CurPage – 1;
lblCurrentPage.Text = “当前页:” + CurPage.ToString();
\n
if (!objPds.IsFirstPage)
lnkPrev.NavigateUrl = Request.CurrentExecutionFilePath + “?Page=” + Convert.ToString(CurPage – 1);
\n
if (!objPds.IsLastPage)
lnkNext.NavigateUrl = Request.CurrentExecutionFilePath + “?Page=” + Convert.ToString(CurPage + 1);
\n
Repeater1.DataSource = objPds;
Repeater1.DataBind();
}
