repeater模糊查询
用Repeater模糊查询，点击查询按钮，结果能够显示。但是查出每次点击下一页按钮时，repeater却显示全部信息。怎么解决？还是让Repeater显示查询结果！！我是用三层架构做的。
代码：using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;
using BLL;
using Model;

namespace StaffSystem
{
  public partial class ModifyStaff : System.Web.UI.Page
  {
  protected void Page_Load(object sender, EventArgs e)
  {
  if (!IsPostBack)
  {
  pds();
  Repeater1.DataSource = pbs;
  Repeater1.DataBind();
  }
  }
  public PagedDataSource pbs;
  public void pds()
  {
  Staff staff = new Staff();
  staff.Name = this.txtName.Text.ToString();
  staff.Sex = this.txtSex.Text.ToString();
  DataSet ds = StaffBLL.GetDS(staff);
  pbs = new PagedDataSource();
  pbs.DataSource = ds.Tables[0].DefaultView;
  pbs.AllowPaging = true;
  pbs.PageSize = 3;
  pbs.CurrentPageIndex = Convert.ToInt32(Request.QueryString["Page"]);
   
  //this.Repeater1.DataSource = ds;
  //this.Repeater1.DataBind();
  }
  protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
  {
  if (e.Item.ItemType == ListItemType.Footer)
  {

  Label labCountPage = (Label)e.Item.FindControl("labCountPage");
  Label labCurrentPage = (Label)e.Item.FindControl("labCurrentPage");
  HyperLink linkFirst = (HyperLink)e.Item.FindControl("linkFirst");
  HyperLink linkPre = (HyperLink)e.Item.FindControl("linkPre");
  HyperLink linkNext = (HyperLink)e.Item.FindControl("linkNext");
  HyperLink linklast = (HyperLink)e.Item.FindControl("linklast");
  linkFirst.Enabled = true;
  linkPre.Enabled = true;
  linkNext.Enabled = true;
  linklast.Enabled = true;
  int pageCount = pbs.PageCount;
  int curCount = pbs.CurrentPageIndex;
  if (curCount <= 0)
  {
  linkFirst.Enabled = false;
  linkPre.Enabled = false;
  linkNext.Enabled = true;
  linklast.Enabled = true;
  }
  else
  {
  linkPre.NavigateUrl = "?Page=" + (curCount - 1);
  }
  if (curCount >= pageCount - 1)
  {
  linkFirst.Enabled = true;
  linkPre.Enabled = true;
  linkNext.Enabled = false;
  linklast.Enabled = false;
  }
  else
  {
  linkNext.NavigateUrl = "?Page=" + (curCount + 1);

  }
  linkFirst.NavigateUrl = "?Page=0";
  linklast.NavigateUrl = "?Page=" + (pageCount - 1);
