分页控件+导航！

一个我经常用到的PageControl，控件的不足之处就是翻页是通过传递page参数的，当在本页面有传递参数的时候会麻烦点。

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            int pageIndex = 1;
            if (Request.Params["page"] != null && Request.Params["page"].ToString() != "")
            {
                Session["pagelog"] = Convert.ToInt32(Request.Params["page"]);
                pageIndex = Convert.ToInt32(Request.Params["page"]);
            }
            else
            {
                if (Session["pagelog"] != null && Session["pagelog"].ToString() != "")
                {
                    pageIndex = Convert.ToInt32(Session["pagelog"]);
                }
                else
                {
                    pageIndex = 1;
                    Session["pagelog"] = 1;
                }
            }
           Binding(pageIndex);     
                    
        }
    }
   
    void Binding(int pageIndex)//绑定用户信息
    { 
        pageIndex--;
        Game.BLL.ha8_member BllMember = new Game.BLL.ha8_member();
        DataSet ds = BllMember.GetList("");
        GV.DataSource = ds;
        int record_Count = ds.Tables[0].Rows.Count;
        int page_Size = GV.PageSize;
        int totalPages = int.Parse(Math.Ceiling((double)record_Count / page_Size).ToString());
        if (totalPages > 0)
        {
            if ((pageIndex + 1) > totalPages)
                pageIndex = totalPages - 1;
        }
        else
        {
            pageIndex = 0;
        }
        GV.CurrentPageIndex = pageIndex;
        GV.DataBind();
        int page_Count = GV.PageCount;
        int page_Current = pageIndex + 1;
        Page01_1.Record_Count = record_Count;
        Page01_1.Page_Count = page_Count;

        Page01_1.Page_Size = page_Size;

        Page01_1.Page_Current = page_Current;     
 
    }
