datalist或gridvie如何实现1234分页

[aixichuan]

我知道datalist可通过添加控件实现“首页 上一页 下一页 尾页”的分页，gridview自带的分页可用实现”1 2 3 4“这样的分页，但是我想实现“首页 上一页 1 2 3 4... 下一页 尾页”这样的分页要怎么实现啊，哪位高手指点下，最好能给出具体代码。注意要“首页 上一页 下一页 尾页”和”1 2 3 4“在同一行显示。

自己做的

三个按钮分别为上一页、下一页、跳至，还有一个文本框,两个标签

Session["dt"]为源数据DT
gv为源GridView


//上一頁
protected void btn_pre_Click(object sender, EventArgs e)
{
pre_page(gv);
}
protected void pre_page(GridView gv)
{
int totalpage = 1;
if (((DataTable)Session["dt"]).Rows.Count % pagesize != 0)
{
totalpage = ((DataTable)Session["dt"]).Rows.Count / pagesize + 1;
}
else
{
totalpage = ((DataTable)Session["dt"]).Rows.Count / pagesize;
}


if (gv.PageIndex > 0)
{
gv.PageIndex -= 1;
gv_bind();
lb_show.Text = "頁碼: <strong style='color:blue'>" + (gv.PageIndex + 1) + "/" + totalpage + "</strong>";
}
else
{
new Tool().WarningDialog("已到達第一頁!");
}
}
//下一頁
protected void btn_next_Click(object sender, EventArgs e)
{
next_page(gv);
}
protected void next_page(GridView gv)
{
int totalpage = 1;
if (((DataTable)Session["dt"]).Rows.Count % pagesize != 0)
{
totalpage = ((DataTable)Session["dt"]).Rows.Count / pagesize + 1;
}
else
{
totalpage = ((DataTable)Session["dt"]).Rows.Count / pagesize;
}

if (gv.PageIndex < totalpage - 1)
{
gv.PageIndex += 1;
gv_bind();
lb_show.Text = "頁碼: <strong style='color:blue'>" + (gv.PageIndex + 1) + "/" + totalpage + "</strong>";
}
else
{
new Tool().WarningDialog("已到達最後一頁!");
}
}

//跳至指定頁
protected void btn_goto_Click(object sender, EventArgs e)
{
int totalpage = 1;
if (((DataTable)Session["dt"]).Rows.Count % pagesize != 0)
{
totalpage = ((DataTable)Session["dt"]).Rows.Count / pagesize + 1;
}
else
{
totalpage = ((DataTable)Session["dt"]).Rows.Count / pagesize;
}

int go = 0;
try
{
go = Convert.ToInt32(tb_goto.Text.Trim());
}
catch
{
new Tool().WarningDialog("請輸入一個整數!");
return;
}
if (go < totalpage + 1 && go > 0)
{

gv.PageIndex = go - 1;
gv_bind();
lb_show.Text = "頁碼: <strong style='color:blue'>" + go + "/" + totalpage + "</strong>";
}
else
{
new Tool().WarningDialog("超出頁面範圍!");
}
}


protected void gv_bind()
{
DataView view = ((DataTable)Session["dt"]).DefaultView;
this.gv.DataSource = view;
this.gv.DataBind();
}
