在做项目的过程中，最初采用Datagrid的默任的分页方式分页，后来发现对于大的数据量速度很慢，NET进程占用系统资源也很大，后来写了个分页的存储过程，每次取数据都只取当前页的，分页是分好了，但是发现翻页就没那么方便了，于是自己写了个简单的分页控件，代码如下(编译以后直接形成dll就可以用)。
程序代码：

using System.Web.UI;
using System.Web.UI.WebControls;
using System.ComponentModel;

namespace PageInfoControl
{
    /// <summary>
    /// WebCustomControl1 的摘要说明。
    /// </summary>
    [DefaultProperty("TotalRecord"),
    ToolboxData("<{0}:PageInfo runat=server></{0}:PageInfo>")]
    public class PageInfo : System.Web.UI.WebControls.WebControl,IPostBackEventHandler
     {
        #region Construct method
        /// <summary>
        /// 构造函数
        /// </summary>
        public PageInfo():base(HtmlTextWriterTag.Div)
        {

        }
        #endregion

        #region Variables and Constants

        public event EventHandler ChangePageClick;
        private string _BarBackGroundColor = "#F1F1F1";

}

控件中有几个相关的属性，在使用的时候，只需要指定：TotalRecord(总记录数)、PageSize(每页的数据记录数)、CurrentPageIndex(当前页面值)、ItemSize(分页条显示页面值的规格)
控件中有个ChangePageClick事件，可以利用“控件ID.CurrentPageIndex”属性来获取当前页面值。
