万能简单GridView分页代码

<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();
    }

dataBinding()为GridViewHistory的数据源绑定事件
