高手们帮我看下这个问题有关AspNetPager 和 搜索的关联问题 小弟在线等 急急急。。。

Question

在搜索出来答案后 用AspNetPager分页 到第二页搜做结果就不管用了  源码如下：
public partial class admin_Manage_news : System.Web.UI.Page
{
   string nid = "";
    DataSet ds;
    SqlDataAdapter dr;
    SqlCommand com;
    SqlConnection myConnection = new SqlConnection(
            ConfigurationManager.ConnectionStrings["SQLCONNECTIONSTRING"].ConnectionString);
    protected void Page_Load(object sender, EventArgs e)
    {
        if ((Session["id"] == "") || (Session["id"] == null))
        {
            Response.Write("<script>alert('" + "用户名已超时，请重新登录！！！" + "');top.window.location.href='Default.aspx';</script>");
        }
        if (Request.Params["id"] != null)
        {
            nid = Request.Params["id"];
        }
        if (!Page.IsPostBack)
        {
            myConnection.Open();
            com = new SqlCommand();
            com.Connection = myConnection;
            com.CommandText = "select count(*) from News where News_catid=" + nid + " ";
            AspNetPager1.AlwaysShow = true;
            AspNetPager1.PageSize = 15;
            AspNetPager1.RecordCount = (int)com.ExecuteScalar();            myConnection.Close();
            bind_news();
        }    }
    public void bind_news()
    {        String cmdText = "SELECT News_id,News_title,News_dateandtime from News WHERE News_catid=" + nid + " ORDER BY News_id DESC ";
        dr = new SqlDataAdapter(cmdText, myConnection);
        ds = new DataSet();
        dr.Fill(ds, AspNetPager1.PageSize * (AspNetPager1.CurrentPageIndex - 1), AspNetPager1.PageSize, "News");
        Show_news.DataSource = ds.Tables["News"];
        Show_news.DataBind();
       
    }
    protected void AspNetPager1_PageChanging(object src, Wuqi.Webdiyer.PageChangingEventArgs e)
    {
        AspNetPager1.CurrentPageIndex = e.NewPageIndex;        bind_news();
    }    protected void Delet_news(object sender, EventArgs e)
    {
        string kk = "";
        foreach (DataListItem item in Show_news.Items)
        {
            HtmlInputCheckBox chkItem = item.FindControl("chkItem") as HtmlInputCheckBox;
            if (chkItem.Checked)
            {
                kk = kk + chkItem.Value + ",";
            }
        }
        string str = kk.Trim(',');        string CmdText = "DELETE FROM [News] WHERE News_id in(" + str + ")";
        SqlCommand myCommand = new SqlCommand(CmdText, myConnection);
        int nResult = -1;
        try
        {
            myConnection.Open();
            nResult = myCommand.ExecuteNonQuery();        }
        catch (SqlException ex)
        {
            throw new Exception(ex.Message, ex);
        }
        finally
        {
            myConnection.Close();
        }
        Response.Write("<script>alert('" + "删除成功" + "');window.location.href='Manage_news.aspx?id="+nid+"';</script>");
    }
    protected void ImageButton1_Click(object sender, ImageClickEventArgs e)
    {
        string CKeyWord = "";
        if (KeyWord.Text == "")
        {
            CKeyWord = "";
        }
        else
        {
            CKeyWord = " and News_title like '%" + KeyWord.Text + "%'";
        }
        myConnection.Open();
        com = new SqlCommand();
        com.Connection = myConnection;
        com.CommandText = "select count(*) from News where News_catid=" + nid + "" + CKeyWord + "";
        AspNetPager1.AlwaysShow = true;
        AspNetPager1.PageSize = 15;
        AspNetPager1.RecordCount = (int)com.ExecuteScalar();        myConnection.Close();
        String cmdText = "SELECT News_id,News_title,News_dateandtime from News WHERE News_catid=" + nid + "" + CKeyWord + "";
        dr = new SqlDataAdapter(cmdText, myConnection);
        ds = new DataSet();
        dr.Fill(ds, AspNetPager1.PageSize * (AspNetPager1.CurrentPageIndex - 1), AspNetPager1.PageSize, "News");
        Show_news.DataSource = ds.Tables["News"];
        Show_news.DataBind();          }
  
}前台部分分页代码：
<webdiyer:AspNetPager ID="AspNetPager1" runat="server"   PageSize="15"  ShowBoxThreshold="1" AlwaysShow="True" FirstPageText="首页" LastPageText="末页"
NextPageText="下一页" PrevPageText="上一页"  onpagechanging="AspNetPager1_PageChanging" UrlPaging="True"  CurrentPageButtonClass="cpb" CurrentPageButtonPosition="Center" NumericButtonCount="10" SubmitButtonText="Go" TextAfterPageIndexBox="页" TextBeforePageIndexBox="转到" Width="577px" UrlRewritePattern='../pagelist_{0}.aspx?&KeyWord="Request("KeyWord")"'  >
  </webdiyer:AspNetPager>

Answer 1

  protected void AspNetPager1_PageChanging(object src, Wuqi.Webdiyer.PageChangingEventArgs e)
    {
        AspNetPager1.CurrentPageIndex = e.NewPageIndex;        bind_news();
    } 
应该是
  protected void AspNetPager1_PageChanged(object src, Wuqi.Webdiyer.PageChangingEventArgs e)
    {
        //AspNetPager1.CurrentPageIndex = e.NewPageIndex;        bind_news();
    } 

Answer 2

还没解决？你的翻页激发的事件不对。打开你的页面设计视图，选中你的分页控件，然后点事件，也就是闪电那图标：双击AspNetPager1_PageChanged事件，在那事件里加 bind_news();
代码为 protected void AspNetPager1_PageChanged(object sender, EventArgs e)
    {
bind_news();
}把这onpagechanging="AspNetPager1_PageChanging"去掉，还有相应的事件也去掉。正确的是onpagechanged="AspNetPager1_PageChanged"。

Answer 3

protected void AspNetPager1_PageChanged(object src, Wuqi.Webdiyer.PageChangingEventArgs e) 
    {         bind_news(); 
    }
