AspNetPager搜索分页问题，急！`````

Question

const string vsKey = "searchCriteria";
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!this.Page.IsPostBack)
        {
             DataBinder(string.Empty);
        }
    } private void DataBinder(string strContext)
    {
        DataSet dscount = BLL.UserInfoBLL.GetUserCount(strContext);
        this.AspNetPager.RecordCount = int.Parse(dscount.Tables[0].Rows[0][0].ToString());
        int startIndex = AspNetPager.CurrentPageIndex;
        DataView dv = BLL.UserInfoBLL.GetUserCountPage(AspNetPager.PageSize, startIndex, strContext);
        PagedDataSource pgs = new PagedDataSource();        pgs.DataSource = dv;
        pgs.AllowPaging = true;
        pgs.CurrentPageIndex = AspNetPager.CurrentPageIndex - 1;
        pgs.PageSize = AspNetPager.PageSize;
        this.Repeater.DataSource = pgs;
        this.Repeater.DataBind();
    }protected void AspNetPager_PageChanged(object src, EventArgs e)
    {
        DataBinder((string)ViewState[vsKey]);
    }
 protected void btnSelect_Click(object sender, EventArgs e)
    {
        AspNetPager.CurrentPageIndex = 1;
        string s = txtSelect.Text.Trim();
        ViewState[vsKey] = s;
        DataBinder(s);
    }不知道是哪里出问题了。这个分页我弄了2天了，还是不行。这代码，基本上就跟例子上的一样的。不知道为啥我这个不行
大家帮忙看一下。解决给分！

Answer 1

还有这个 <webdiyer:AspNetPager ID="AspNetPager" OnPageChanged="AspNetPager_PageChanged" runat="server"
            HorizontalAlign="Center" PagingButtonSpacing="8Px" UrlPaging="true" UrlPageIndexName="p"
            PageSize="7" CssClass="pages" CurrentPageButtonClass="cpb" FirstPageText="首页"
            LastPageText="末页" NextPageText="下一页" PrevPageText="上一页" ShowMoreButtons="false"
            ShowPageIndexBox="Never" AlwaysShow="true">
        </webdiyer:AspNetPager>

Answer 2

this.AspNetPager.RecordCount = int.Parse(dscount.Tables[0].Rows[0][0].ToString()); 这个应该有误吧。
this.AspNetPager.RecordCount = dscount. Items.Count;

Answer 3

不是额 dscount 是我专门查询 总记录数的， select count（*） from table  

Answer 4

protected void AspNetPager_PageChanged(object src, EventArgs e)
  {
  DataBinder((string)ViewState[vsKey], this.AspNetPager1.StartRecordIndex - 1));
  }
 分页你也要知道取第多少条记录把。

Answer 5

前台<div>
        <asp:GridView ID="gdvData" runat="server" CellPadding="4" ForeColor="#333333" GridLines="None"
            Width="100%">
            <FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
            <RowStyle BackColor="#EFF3FB" />
            <EditRowStyle BackColor="#2461BF" />
            <SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
            <PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
            <HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
            <AlternatingRowStyle BackColor="White" />
        </asp:GridView>
        <webdiyer:aspnetpager id="AspNetPager1" runat="server" PageSize="5" AlwaysShow="True" OnPageChanged="AspNetPager1_PageChanged" ShowCustomInfoSection="Left" CustomInfoSectionWidth="40%" ShowPageIndexBox="always" PageIndexBoxType="TextBox"
    CustomInfoHTML="第<font color='red'><b>%currentPageIndex%</b></font>页，共%PageCount%页" Width="100%"></webdiyer:aspnetpager>
    </div>后台：protected void Page_Load(object sender, EventArgs e)
    {
        if(!IsPostBack)
        {
            AspNetPager1.RecordCount = DBHelper.GetCount();//得到数据的总数
            this.gdvDataBind();//绑定
        }
}
protected void AspNetPager1_PageChanged(object sender, EventArgs e)
    {
        this.gdvDataBind();
    }    protected void gdvDataBind()
    {
        this.gdvData.DataSource = DBHelper.GetKbhelpQuestion(AspNetPager1.PageSize, AspNetPager1.CurrentPageIndex,0,0,0,0,"","","ID");//GetKbhelpQuestion方法里面用的是分页存储过程
        this.gdvData.DataBind();
    }

Answer 6

public string strFlag
{
get{return viewstate["strflag"].toString();}
set{viewstate["strflag"]=value;}
}
在点击搜索的时候strFlag=txtSelect.Text.Trim();
private void DataBinder(string strContext)不要参数，直接把strContext改成strFlag。
试试

没有看 你的 代码 
参考我的 
-------------------------------------

Answer 9

如果用Url的方式分页，每次都是重新打开页面，没有postback，控件的值和viewstate都会清空。
所以只有2个办法
1是改用postback的方式分页
2如果必须用url的方式，那么必须把需要保持的状态通过url传递，然后在打开页面时解析url得到状态。你可以看下google怎么分页的

Answer 10

            AspNetPager1.PageSize = PageSize;
            AspNetPager1.RecordCount = recordCount;
            AspNetPager1.UrlPaging = true;
            AspNetPager1.EnableUrlRewriting = true;
            AspNetPager1.UrlRewritePattern = "Itemlist.aspx?pageIndex={0}&key=" + txtKey.Value+
                                                                        "&ClassId=" + HidClassId.Value + 
                                                                        "&second=" + Hidsecond.Value + 
                                                                        "&AdminId=" + selAdminId.SelectedValue + 
                                                                        "&Shelf=" + ddlShelf.SelectedValue +
                                                                        "&isend=" + Hidfiled.Value + "";
            AspNetPager1.ShowPageIndexBox = Wuqi.Webdiyer.ShowPageIndexBox.Always;
            AspNetPager1.PageIndexBoxType = Wuqi.Webdiyer.PageIndexBoxType.TextBox;

Answer 11

AspNetPager.CurrentPageIndex = 1这句话去掉

Answer 12

protected void Page_Load(object sender, EventArgs e)
    {
            int totalOrders = NewPLManager.GetAllByStu(nid).Count;
            AspNetPager1.RecordCount = totalOrders;
            this.AspNetPager1.PageSize = 8; // 每页显示X条记录
}    #region 分页显示数据
    void bindData()
    {
        //分页查询方法
        int nid = Convert.ToInt32(Request.QueryString["nid"]);
        Repeater1.DataSource = (List<NewPL>)NewPLManager.AdminPage(AspNetPager1.StartRecordIndex, AspNetPager1.EndRecordIndex, nid);
        Repeater1.DataBind();//数据绑定
    }
    protected void AspNetPager1_PageChanged(object src, EventArgs e)
    {
        bindData();
    }
    #endregion
代码都贴给你了 .. 把一些方法改掉就可以了

Answer 13

int nid = Convert.ToInt32(Request.QueryString["nid"]);
这是啥意思啊？

Answer 14

你用了PagesDataSource类了 还用AspNetPager干啥，脱裤子放屁啊。两个都是分页的，自找麻烦

Answer 15

我不懂额，这是看那个aspnetpager控件自带的例子里面这样搞的，不过不知道啥意思。

Answer 17

const string vsKey = "searchCriteria";
  protected void Page_Load(object sender, EventArgs e)
  {
  if (!this.Page.IsPostBack)
  {
  ViewState[vsKey]=Request.QueryString["SearchFor"];
  DataBinder(Request.QueryString["SearchFor"]);
  }
  } private void DataBinder(string strContext)
  {
  DataSet dscount = BLL.UserInfoBLL.GetUserCount(strContext);
  this.AspNetPager.RecordCount = int.Parse(dscount.Tables[0].Rows[0][0].ToString());
  int startIndex = AspNetPager.CurrentPageIndex;
  DataView dv = BLL.UserInfoBLL.GetUserCountPage(AspNetPager.PageSize, startIndex, strContext);
  PagedDataSource pgs = new PagedDataSource();  pgs.DataSource = dv;
  pgs.AllowPaging = true;
  pgs.CurrentPageIndex = AspNetPager.CurrentPageIndex - 1;
  pgs.PageSize = AspNetPager.PageSize;
  this.Repeater.DataSource = pgs;
  this.Repeater.DataBind();
  }protected void AspNetPager_PageChanged(object src, EventArgs e)
  {
  DataBinder((string)ViewState[vsKey]);
  }
 protected void btnSelect_Click(object sender, EventArgs e)
  { 
  string s = txtSelect.Text.Trim();
  Response.Redirect(Request.Path+"?SearchFor="+HttpUtility.UrlEncode(s),true);
  }
AspNetPager_PageChanged可以去掉，Url方式可能不会触发AspNetPager_PageChanged事件。
