本文详细介绍了如何在ASP.NET中使用GridView组件实现分页功能，包括自定义 pager 模板和后台事件处理。通过`GridViewHistory`实例，展示了如何控制页码切换，以及关键的PageIndexChanging和Button_click事件处理。

<asp:GridView ID="GridViewHistory" runat="server" AutoGenerateColumns="False" 
CssClass="vip_table" GridLines="None" BorderStyle="None" CellPadding="0" 
ShowHeader="False" AllowPaging="true" PageSize="20" 
onpageindexchanging="GridViewHistory_PageIndexChanging"> 
<PagerTemplate> 
<asp:LinkButton ID="lb_firstpage" runat="server" onclick="lb_firstpage_Click">首页</asp:LinkButton> 
<asp:LinkButton ID="lb_previouspage" runat="server" onclick="lb_previouspage_Click">上一页</asp:LinkButton> 
<asp:LinkButton ID="lb_nextpage" runat="server" onclick="lb_nextpage_Click">下一页</asp:LinkButton> 
<asp:LinkButton ID="lb_lastpage" runat="server" onclick="lb_lastpage_Click">尾页</asp:LinkButton> 
第<asp:Label ID="lbl_nowpage" runat="server" Text="<%#GridViewHistory.PageIndex+1 %>" ForeColor="#db530f"></asp:Label>页/共<asp:Label ID="lbl_totalpage" runat="server" Text="<%#GridViewHistory.PageCount %>" ForeColor="#db530f"></asp:Label>页 
</PagerTemplate>

后台代码

//分页 
protected void GridViewHistory_PageIndexChanging(object sender, GridViewPageEventArgs e) 
{ 
GridViewHistory.PageIndex = e.NewPageIndex; 
dataBinding(); 
} 
protected void Button_search_Click(object sender, EventArgs e) 
{ 
dataBinding(); 
} 
protected void lb_firstpage_Click(object sender, EventArgs e) 
{ 
this.GridViewHistory.PageIndex = 0; 
dataBinding(); 
} 
protected void lb_previouspage_Click(object sender, EventArgs e) 
{ 
if (this.GridViewHistory.PageIndex > 0) 
{ 
this.GridViewHistory.PageIndex--; 
dataBinding(); 
} 
} 
protected void lb_nextpage_Click(object sender, EventArgs e) 
{ 
if (this.GridViewHistory.PageIndex < this.GridViewHistory.PageCount) 
{ 
this.GridViewHistory.PageIndex++; 
dataBinding(); 
} 
} 
protected void lb_lastpage_Click(object sender, EventArgs e) 
{ 
this.GridViewHistory.PageIndex = this.GridViewHistory.PageCount; 
dataBinding(); 
}
