GridView 分页

        给大家分享下我自认为GridView 最简单的分页，

前台代码：

         <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" >
        <Columns>
            <asp:TemplateField HeaderText="标题"> <ItemTemplate><%# Eval("title") %></ItemTemplate>
                <HeaderStyle HorizontalAlign="Center" Width="200px" />
                <ItemStyle HorizontalAlign="Center" />
            </asp:TemplateField>
            <asp:TemplateField HeaderText="产品简介"> <ItemTemplate><%# Eval("conter") %></ItemTemplate>
                <HeaderStyle HorizontalAlign="Center" />
                <ItemStyle HorizontalAlign="Center" />
            </asp:TemplateField>
            <asp:TemplateField HeaderText="下载">
                <ItemTemplate>
                   <a href='<%# Eval("address") %>'>下载</a>
                </ItemTemplate>
                <ControlStyle Font-Bold="True" Font-Overline="True" />
                <HeaderStyle HorizontalAlign="Center" Width="200px" />
                <ItemStyle HorizontalAlign="Center" />
            </asp:TemplateField>
        </Columns>
        <RowStyle Height="35px" />
    </asp:GridView>

     <div style="float:right">
        <asp:HyperLink ID="HyperLink1" runat="server">首页</asp:HyperLink>
        <asp:HyperLink ID="HyperLink2" runat="server">上一页</asp:HyperLink>
        <asp:HyperLink ID="HyperLink3" runat="server">下一页</asp:HyperLink>
        <asp:HyperLink ID="HyperLink4" runat="server">尾页</asp:HyperLink>
    </div>

后台代码：

          protected void Bind()
        {
            //定义记录总数
            //int total;
            //定义当前页码
            int pageindex;
            //获取当前页码(从查询字符串中获取)
            if (!int.TryParse(Request.QueryString["page"], out pageindex))
            {
                pageindex = 1;
            }
            

            //11为显示的当前页显示11条记录。
            //获取指定类别,指定页码的数据,并进行绑定显示
            GridView1.DataSource = DownManager.GetsPage(pageindex, 11);
            GridView1.DataBind();
            //计算总的页数
            int totalpage = (int)Math.Ceiling(Convert.ToDouble(DownManager.getsNum()) / 11F);
            //NavigateUrl 获取或者设置链接目标
            //设置分页
            HyperLink1.NavigateUrl = "./GoodsDown.aspx?goodsId=" + Request.QueryString["id"];
            HyperLink2.NavigateUrl = "./GoodsDown.aspx?goodsId=" + Request.QueryString["id"] + "&page=" + (pageindex > 1 ? pageindex - 1 : 1);
            HyperLink3.NavigateUrl = "./GoodsDown.aspx?goodsId=" + Request.QueryString["id"] + "&page=" + (pageindex < totalpage ? pageindex + 1 : totalpage);
            HyperLink4.NavigateUrl = "./GoodsDown.aspx?goodsId=" + Request.QueryString["id"] + "&page=" + totalpage;
           
        }

注：page  id 值的获取。
