asp.net+access 怎么用aspnetpager分页
C# code

string accessConnection = ConfigurationManager.ConnectionStrings["accessConnection"].ConnectionString;



------解决方案--------------------
给个例子给你

C# code

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            this.AspNetPager1.PageSize = 10;

            this.AspNetPager1.RecordCount = Convert.ToInt32(OpenCode.AccessHelper.GetExecuteScalar("select count(*) from news as a inner join newstype as b on(a.ntypeid=b.ntid) where a.nlanguage=0 ", null));

            GridDataBinds(1);
        }
    }

    private void GridDataBinds(int pageIndex)
    {
        int pageSize = this.AspNetPager1.PageSize;
        string strSql = PageCode.GetCommonPaging(" select top 10 nid,ntitle,ncontents,ndate,ntname,nrecommend,nsequence from news as a inner join newstype as b on(a.ntypeid=b.ntid)",
                                                 pageSize, pageIndex, "nid", " and a.nlanguage=0 ", "from news as a inner join newstype as b on(a.ntypeid=b.ntid) ");

        this.GridView1.DataSource = OpenCode.AccessHelper.GetReader(strSql, null);
        this.GridView1.DataKeyField = "nid";
        this.GridView1.DataBind();
    }

    protected void AspNetPager1_PageChanging(object src, Wuqi.Webdiyer.PageChangingEventArgs e)
    {
        GridDataBinds(e.NewPageIndex);
    }


封转方法

 /// <summary>
    /// 拼凑分页语句
    /// </summary>
    /// <param name="strSql">sql语句</param>
    /// <param name="strtab">表名</param>
    /// <param name="pageSize">分页大小</param>
    /// <param name="pageIndex">当前页</param>
    /// <param name="orderfield">排序字段</param>
    /// <returns></returns>
    public static string GetCommonPaging(string strSql, string strtab, int pageSize, int pageIndex, string orderfield,string strWhere)
    {
        string str = "";
        if (pageIndex > 1)
        {
            str = string.Format("{0} where 1=1 {4} and {1}>( select max({1}) " +
                                             " from( select top {2} {1} from {3}  where 1=1 {4} order by {1}) as {1} ) order by {1} ",
                                               strSql, orderfield, (pageSize * (pageIndex - 1)).ToString(), strtab, strWhere);

        }
        else
        {
            str = string.Format("{0} order by {1}", strSql, orderfield);
        }

        return str;
    }

    public static string GetCommonPaging(string strSql, int pageSize, int pageIndex, string orderfield, string strWhere,string strchild)
    {
        string str = "";
        if (pageIndex > 1)
        {
            str = string.Format("{0} where 1=1 {3} and {1}>( select max({1}) " +
                                             " from( select top {2} {1} {4} where 1=1 {3} order by {1}) as {1} ) order by {1} ",
                                               strSql, orderfield, (pageSize * (pageIndex - 1)).ToString(), strWhere, strchild);

        }
        else
        {
            str = string.Format("{0} where 1=1 {2} order by {1}", strSql, orderfield, strWhere);
        }

        return str;
    }


PS
   分页语句原型:

[code=SQL]
SELECT TOP 页大小 *
FROM table1
WHERE id >
          (
          SELECT ISNULL(MAX(id),0) 
          FROM 
                (
                SELECT TOP 页大小*(页数-1) id FROM table1 ORDER BY id
                ) A
          )
ORDER BY id
