aspnetpager 分页后为什么只有一页

    protected void Page_Load(object sender, EventArgs e)

    {

        if (!Page.IsPostBack)

        {

            Bing();

        }

       

    }





    protected void Bing() 

    {



        string s = "server=.\\sql2005;database=test;uid=sa;pwd=123456;";

        SqlConnection conn = new SqlConnection(s);

        string sql = "select * from [user]";

        SqlCommand cmd = new SqlCommand(sql, conn);

        SqlDataAdapter sda = new SqlDataAdapter(sql, conn);

        

        DataSet Set = new DataSet();

        sda.Fill(Set);





        PagedDataSource pds = new PagedDataSource();

        pds.AllowPaging = true;

        pds.PageSize = AspNetPager1.PageSize;

        pds.CurrentPageIndex = AspNetPager1.CurrentPageIndex - 1;

        pds.DataSource = Set.Tables[0].DefaultView;

        gv.DataSource = pds;

        gv.DataBind();



    

    }







    protected void AspNetPager1_PageChanged(object sender, EventArgs e)

    {

       

        Bing();

    }
