Next previous first last pager in ASP.Net

Hi

I have datalist in my page and I use pagination for my data list:

 private void GetCustomersPageWise(int pageIndex)
    {



        if (Request.QueryString["H_name"] != "all")
        {

            string BehCode = "";
            using (SqlCommand cmd = new SqlCommand("GetCustomersPageWise1", _cn))
            {



                if (!(Request.QueryString["H_name"] == null))
                {
                    BehCode = Request.QueryString["H_name"];
                    lblmain.Visible = true;
                    Label1.Visible = false;
                   
                }
                else if (!(Request.QueryString["subset"] == null))
                {
                    BehCode = Request.QueryString["subset"];
                    lblmain.Visible = false;
                    Label1.Visible = true;
                }
             

                cmd.CommandType = CommandType.StoredProcedure;
                string data1 = Request.QueryString["id"].ToString();
                cmd.Parameters.AddWithValue("@id",data1);
                cmd.Parameters.AddWithValue("@H_name", BehCode);
                cmd.Parameters.AddWithValue("@subset", BehCode);
                cmd.Parameters.AddWithValue("@Region", DDLzone1.SelectedItem.Text);

                _cn.Open();
                IDataReader idr = cmd.ExecuteReader();
                DataList1.DataSource = idr;
                DataList1.DataBind();
                idr.Close();
                _cn.Close();
                int recordCount = Convert.ToInt32(cmd.Parameters["@RecordCount"].Value);
           
                this.PopulatePager(recordCount, pageIndex);
            }
        }
        else
        {
            using (SqlCommand cmd = new SqlCommand("GetCustomersPageWise", _cn))
            {
                cmd.CommandType = CommandType.StoredProcedure;
                cmd.Parameters.AddWithValue("@PageIndex", pageIndex);
                cmd.Parameters.AddWithValue("@PageSize", PageSize);
                cmd.Parameters.Add("@RecordCount", SqlDbType.Int, 4);
                cmd.Parameters.AddWithValue("@Region", DDLzone1.SelectedItem.Text);
    DDLstore1.SelectedItem.Text.Trim());
                cmd.Parameters["@RecordCount"].Direction = ParameterDirection.Output;
                _cn.Open();
                IDataReader idr = cmd.ExecuteReader();
                DataList1.DataSource = idr;
                DataList1.DataBind();
                idr.Close();
                _cn.Close();
                int recordCount = Convert.ToInt32(cmd.Parameters["@RecordCount"].Value);
         
                this.PopulatePager(recordCount, pageIndex);
            }

        }


    }









    protected void Page_Changed(object sender, EventArgs e)
    {
        int pageIndex = int.Parse((sender as LinkButton).CommandArgument);
        this.GetCustomersPageWise(pageIndex);
    }




    private void PopulatePager(int recordCount, int currentPage)
    {
        double dblPageCount = (double)((decimal)recordCount / (decimal)PageSize);
        int pageCount = (int)Math.Ceiling(dblPageCount);
        List<ListItem> pages = new List<ListItem>();
        if (pageCount > 0)
        {
            pages.Add(new ListItem("<<", "1", currentPage > 1));
            if (currentPage != 1)
            {
                pages.Add(new ListItem("Previous", (currentPage - 1).ToString()));
            }
            for (int i = 1; i <= pageCount; i++)
            {
                pages.Add(new ListItem(i.ToString(), i.ToString(), i != currentPage));
            }
            if (currentPage != pageCount)
            {
                pages.Add(new ListItem("next", (currentPage + 1).ToString()));
            }
            pages.Add(new ListItem(">>", pageCount.ToString(), currentPage < pageCount));
        }
        rptPager.DataSource = pages;
        rptPager.DataBind();
    }

ok this pagination is like below

<< next 1 2 3 4 5 6 7 8 9 10   Previuos >>

 it show all pages

I want datalist pagination be like below

<< Next 1 2 3 4 ... Previous >> 

and when i click on 4 it change like below

<< Next ... 5 6 7 8 9 10 Previous >>

Or some thing like that I mean I want some Pagination that doesn't show all pages

How I can do it?

Thanks
