1.  放个Label1 两个    Button1 Button2
    在pagLond 事件里
    设成 Label1.Text = "1";  //显示当前页
2. 代码:
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            Label1.Text = "1";
            getBangDing();
        }
    }
    private void getBangDing()
    {
        int num = Convert.ToInt32(Label1.Text);
        SqlConnection con = new SqlConnection("连接字符串");
        con.Open();
        SqlDataAdapter da = new SqlDataAdapter("sql语句", con);
        DataSet set = new DataSet();
        da.Fill(set, "table");

        PagedDataSource pds = new PagedDataSource();
        pds.DataSource = set.Tables["table"].DefaultView;
        pds.AllowPaging = true;
        pds.PageSize = 3;
        int countNum=pds.PageCount;
        pds.CurrentPageIndex = num - 1;
        Button1.Enabled = true;
        Button2.Enabled = true;
        if (num == 1)
        {
            Button1.Enabled = false;
        }
        if (num == countNum)
        {
            Button2.Enabled = false;
        }
        Repeater1.DataSource = pds;
        Repeater1.DataBind();
    }
   protected void Button1_Click(object sender, EventArgs e)
    {
        Label1.Text = Convert.ToString(Convert.ToInt32(Label1.Text) -1); ///上一页
        getBangDing();
    }
    protected void Button2_Click(object sender, EventArgs e)
    {
        Label1.Text = Convert.ToString(Convert.ToInt32(Label1.Text) + 1);///下一页
        getBangDing();
    }
