用结合ajax control toolket的控件 做了个搜索页面,,根据不同的类别,因为每个目标数据库表的结构不一样所以,用了3个gridview控件,分别来显示这3个类别的搜索结果,结果gridview控件分页出现问题
前台代码
<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="SearchResult.aspx.cs" Inherits="SearchResult" Title="搜索结果页" Theme="typical"%>

</asp:ScriptManagerProxy>
<div class="bodydiv01" id="searchdivbox">
<div class="searchheader">
关键字: <asp:TextBox ID="txtKeyword" runat="server"></asp:TextBox>
类别:
<asp:DropDownList ID="DropDownList1" runat="server">
<asp:ListItem Selected="True" Value="articles">文章</asp:ListItem>
<asp:ListItem Value="downloads">下载资源</asp:ListItem>
<asp:ListItem Value="links">链接</asp:ListItem>

每页条数:<asp:TextBox ID="txtNum" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="立刻搜索" OnClick="Button1_Click" /> [/color[color=#0000FF]]//此处点击后可以显示数据,分页器也能显示,只是点击 页码 1以后的页码,页面gridview就为空了

------解决方案--------------------------------------------------------
AspNetPager1.PageSize = pageSize;
AspNetPager1.RecordCount = RecordCount;
AspNetPager1.CurrentPageIndex = pageIndex;
AspNetPager1.DataBind();
是不是少了：AspNetPager1.RecordCount = RecordCount；？
------解决方案--------------------------------------------------------
用的这 AspNetPager 这个控件，好多了。又方便又好用。

这样试试
- C# code
protected void ArtilceView_PageIndexChanging(object sender, GridViewPageEventArgs e) { ArtilceView.PageIndex = e.NewPageIndex; ArtilceView.Visible = true; ShowData("articles")； } protected void DownloadList_PageIndexChanging(object sender, GridViewPageEventArgs e) { DownloadList.PageIndex = e.NewPageIndex; ShowData("downloads"); } protected void Links_PageIndexChanging(object sender, GridViewPageEventArgs e) { Links.PageIndex = e.NewPageIndex; ShowData("links")； }
