小白不会使用AspNetPager,请高人指教!
C# code

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            int totalOrders = (int)SqlHelper.ExecuteScalar(CommandType.StoredProcedure, "P_GetOrderNumber");
            AspNetPager1.RecordCount = totalOrders;
            //bindData(); //使用url分页,只需在分页事件处理程序中绑定数据即可,无需在Page_Load中绑定,否则会导致数据被绑定两次
        }
    }

    void bindData()
    {
        Repeater1.DataSource = SqlHelper.ExecuteReader(CommandType.StoredProcedure, ConfigurationManager.AppSettings["pagedSPName"],
            new SqlParameter("@startIndex", AspNetPager1.StartRecordIndex),
            new SqlParameter("@endIndex", AspNetPager1.EndRecordIndex));
        Repeater1.DataBind();
    }

    protected void AspNetPager1_PageChanged(object src, EventArgs e)
    {
        bindData();
    }



这是官方给的Repeater的事例,我基本能看懂。问题是我太菜了他用了存储过程,我根本不懂存储过程。

第一 Page_Load的时候我没理解错应该是先取出记录总数,这个就不会了。
第二 绑定数据的时候他用的存储过程,我想改成不用存储过程传统的绑定就不会了。
