求分页方法Repeater

    //声明一个页面数据源，用来缓存信息列表（所有的信息）
    PagedDataSource pds = new PagedDataSource();
    public void DataBind()
    {
        pds.DataSource = noticeMessage.getAllLaw();
        pds.AllowPaging = true;
        pds.PageSize = 3;

        pds.CurrentPageIndex = Pager;
        this.Label4.Text = "第 " + (pds.CurrentPageIndex + 1) + " 页，共 " + (pds.PageCount) + " 页";

        //设置PageDown / PageUp 按钮的状态
        this.Button3.Enabled = true;
        this.Button4.Enabled = true;

        if (pds.IsFirstPage)
            this.Button3.Enabled = false;
        if (pds.IsLastPage)
            this.Button4.Enabled = false;

        //控件绑定信息
        this.rep.DataSource = pds;
        this.rep.DataBind();

    }

    //声明一个变量保存当前页码
    public int Pager
    {
        get { return (int)ViewState["Pager"]; }
        set { ViewState["Pager"] = value; }
    }
