木星上行着在线观看:用datalist如何实现分页的代码（C#）

OleDbConnection MyConn;
int PageSize,RecordCount,PageCount,CurrentPage;
public void Page_Load(Object src,EventArgs e)
{
PageSize = 10 // 根据实际定义常量
string MyConnString = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source="+Server.MapPath(".")+"..\\DataBase\\db1.mdb;";
MyConn = new OleDbConnection(MyConnString);
MyConn.Open();
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();
}
html里的控件id自己对应写好!应该没有问题的。

1编辑好各个模板
2添加实现页跳转的控件，一般为按钮类控件，如LinkButton
3获取、设者或计算所有记录数目、每页显示数目和页数
4从数据库中读取一页数目的记录到DataSet中
5将DataList绑定到数据源DataSet上
6处理分页。
（1）根据不同的命令参数设置当前页
（2）将当前页使用ViewState保存起来
（3）重新获取下一页的数据并重新绑定DataList的数据
（4）重新绑定当前的页码
（5）控制页面导向按钮的可见性
