AspNetPager是一款优秀的分页控件，使用该控件进行数据源分页，关键是设置该控件的RecordCount、StartRecordIndex和EndRecordIndex属性和处理PageChanged事件。

主要代码如下：

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            AspNetPager1.RecordCount = GetRecordCount();//总记录数
            Bind();
        }
    }
    void Bind()
    {
        DataTable dt = new DataTable();
        using (SqlConnection conn = new SqlConnection(@"server=.\sqlexpress;database=北风贸易;uid=sa;pwd=sa"))
        {
            SqlCommand cmd = new SqlCommand("GetPageData", conn);
            cmd.Parameters.AddWithValue("@startIndex", AspNetPager1.StartRecordIndex);
            cmd.Parameters.AddWithValue("@endIndex", AspNetPager1.EndRecordIndex);
            cmd.CommandType = CommandType.StoredProcedure;
            conn.Open();
            SqlDataReader dr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
            dt.Load(dr);
            dr.Close();       
            GridView1.DataSource = dt;
            GridView1.DataBind();
        }

    }
    int GetRecordCount()
    {
        string sql="select count(*) from 产品资料";
        int n=0;
        using(SqlConnection conn=new SqlConnection(@"server=.\sqlexpress;database=北风贸易;uid=sa;pwd=sa"))
        {
            SqlCommand cmd=new SqlCommand(sql,conn);
            conn.Open();
            n=(int)cmd.ExecuteScalar();
        }
        return n;
    }

    protected void AspNetPager1_PageChanged(object sender, EventArgs e)
    {
        Bind();
    }

对应的存储过程如下：

create procedure GetPageData
(@startIndex int,
@endIndex int
)
as
begin
 with temptbl as (
SELECT ROW_NUMBER() OVER (ORDER BY 单价 desc)AS Row, * from 产品资料 )
 SELECT * FROM temptbl where Row between @startIndex and @endIndex
end

该存储过程可以使用AspNetPager自动产生，只需填入信息即可：
