DATALIST 绑定数据分页显示，不像GRIDVIEW 那样自带翻页功能，所以只能通过数据库存过翻页或者前台代码分页，下面是前台代码分页的源码：
<% @ Page Language="C#" %>
<% @ Import Namespace="System.Data" %>
<% @ Import Namespace="System.Data.OleDb" %>
<Script Language="C#" Runat="Server">
OleDbConnection MyConn;
int PageSize,RecordCount,PageCount,CurrentPage;
public void Page_Load(Object src,EventArgs e)
{
//设定PageSize
PageSize = 5;
//连接语句
string MyConnString = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source="+Server.MapPath(".")+"..\\DataBase\\db1.mdb;";
MyConn = new OleDbConnection(MyConnString);
MyConn.Open();
//第一次请求执行
if(!Page.IsPostBack)
{
ListBind();
CurrentPage = 0;
ViewState["PageIndex"] = 0;
//计算总共有多少记录
RecordCount = CalculateRecord();
lblRecordCount.Text = RecordCount.ToString();
//计算总共有多少页
PageCount = RecordCount/PageSize;
lblPageCount.Text = PageCount.ToString();
ViewState["PageCount"] = PageCount;
}
}
//计算总共有多少条记录
public int CalculateRecord()
{
int intCount;
string strCount = "select count(*) as co from Score";
OleDbCommand MyComm = new OleDbCommand(strCount,MyConn);
OleDbDataReader dr = MyComm.ExecuteReader();
if(dr.Read())
{
intCount = Int32.Parse(dr["co"].ToString());
}
else
{
intCount = 0;
}
dr.Close();
return intCount;
}
ICollection CreateSource()
{
int StartIndex;
//设定导入的起终地址
StartIndex = CurrentPage*PageSize;
string strSel = "select * from Score";
DataSet ds = new DataSet();
OleDbDataAdapter MyAdapter = new OleDbDataAdapter(strSel,MyConn);
MyAdapter.Fill(ds,StartIndex,PageSize,"Score");
return ds.Tables["Score"].DefaultView;
}
public void ListBind()
{
score.DataSource = CreateSource();
score.DataBind();
lbnNextPage.Enabled = true;
lbnPrevPage.Enabled = true;
if(CurrentPage==(PageCount-1)) lbnNextPage.Enabled = false;
if(CurrentPage==0) lbnPrevPage.Enabled = false;
lblCurrentPage.Text = (CurrentPage+1).ToString();
}
public void Page_OnClick(Object sender,CommandEventArgs e)
{
CurrentPage = (int)ViewState["PageIndex"];
PageCount = (int)ViewState["PageCount"];
string cmd = e.CommandName;
//判断cmd，以判定翻页方向
switch(cmd)
{
case "next":
if(CurrentPage<(PageCount-1)) CurrentPage++;
break;
case "prev":
if(CurrentPage>0) CurrentPage--;
break;
}
ViewState["PageIndex"] = CurrentPage;
ListBind();
}
