Datalist翻页（不用第三方控件，自己写翻页代码）

1控件准备：2个Label 一个用来绑定第几页，一个用来绑定总页数；5个linkbutton 分别为（首页、上一页、下一页、尾页、Go）；1个textbox用来绑定跳转到的页数

2代码：首先在Page_load事件里面声明刚开始的页数为1，(注意：一定要在非回传页面下) 即          //非回传，非常重要           if (!IsPostBack)            {                Lcount.Text = "1";                MoreBind();            }      // 绑定数据：   public void CheckBind()    {        Infos i = new Infos();        string tile = Ttile.Text;        string content = Tcontent.Text;        string puser = Tpuser.Text;        //第几页        int CurPage= Convert.ToInt32(Lcount.Text);        //当前页面从Page查询参数获取                   PagedDataSource ps = new PagedDataSource();        ps.DataSource = i.QT_Select(tile, content, puser).DefaultView;        ps.AllowPaging = true;        ps.PageSize = 10;        ps.CurrentPageIndex = CurPage - 1;        //绑定总页数        Lsl.Text = ps.PageCount.ToString();        if (ps.IsFirstPage)        {            Lfrist.Enabled = false;            Lpev.Enabled = false;        }        else        {            Lfrist.Enabled = true;            Lpev.Enabled = true;        }        if (ps.IsLastPage)        {            Lnext.Enabled = false;            Llast.Enabled = false;        }        else        {            Lnext.Enabled = true;            Llast.Enabled = true;        }        DlMore.DataSource = ps;        DlMore.DataBind();    }3 5个linkbutton 的单击事件：    //首页    protected void Lfrist_Click(object sender, EventArgs e)    {        Lcount.Text = "1";        CheckBind();    }    //上一页    protected void Lpev_Click(object sender, EventArgs e)    {        Lcount.Text = Convert.ToString(Convert.ToInt32(Lcount.Text) - 1);        CheckBind();    }    //下一页    protected void Lnext_Click(object sender, EventArgs e)    {        Lcount.Text = Convert.ToString(Convert.ToInt32(Lcount.Text) + 1);        CheckBind();    }    //尾页    protected void Llast_Click(object sender, EventArgs e)    {        Lcount.Text = Lsl.Text;        CheckBind();    }    //跳转    protected void LGo_Click(object sender, EventArgs e)    {        if (Convert.ToInt32(TGO.Text) >= 1 && Convert.ToInt32(TGO.Text) <= Convert.ToInt32(Lsl.Text))        {            Lcount.Text = TGO.Text;        }        else        {            Response.Write("<script>alert('请输入正确页数！');</script>");        }        CheckBind();        TGO.Text = "";    }
