GridView 分页通用方法

来源：互联网发布：网络安全设备维保方案编辑：程序博客网时间：2024/05/08 04:35

1、增加以下GridView属性：

AllowPaging="true" //启用分页

PageSize="10" //每页显示10条数据

OnPageIndexChanging="gv_tclist_PageIndexChanging" //分页时触发的事件

2、分页时触发事件代码

protected void gv_tclist_PageIndexChanging(object sender, GridViewPageEventArgs e)        {            gv_tclist.PageIndex = e.NewPageIndex;            GetTCList(); //获取GridView数据源        }

3、通用的分页模版(可以自己调整结构)

<PagerTemplate>                <table width="100%" class="tableheader">                    <tr>                        <td align="left">                            <asp:LinkButton ID="LinkButtonFirstPage" runat="server" CommandArgument="First" CommandName="Page"                                Enabled="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">首页</asp:LinkButton>                            <asp:LinkButton ID="LinkButtonPreviousPage" runat="server" CommandArgument="Prev"                                CommandName="Page" Enabled="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">上一页</asp:LinkButton>                            <asp:LinkButton ID="LinkButtonNextPage" runat="server" CommandArgument="Next" CommandName="Page"                                Enabled="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">下一页</asp:LinkButton>                            <asp:LinkButton ID="LinkButtonLastPage" runat="server" CommandArgument="Last" CommandName="Page"                                Enabled="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">尾页</asp:LinkButton>                            <a id="CurrentPage">第</a>                            <asp:Label ID="LabelCurrentPage" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageIndex + 1 %>"></asp:Label>                            /<asp:Label ID="LabelPageCount" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageCount %>"></asp:Label>页                             每页<asp:Label ID="LabelPageSize" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageSize %>"></asp:Label>条                             到第<asp:TextBox runat="server" ID="inPageNum" Rows="3" Columns="3" EnableViewState="true"></asp:TextBox>页                            <asp:Button ID="Button1" CommandName="go" Text="GO" CssClass="btn_2k3" runat="server" />                        </td>                        <td align="right">                        </td>                    </tr>                </table>            </PagerTemplate>

4、模版中对应的按钮事件

protected void gv_tclist_RowCommand(object sender, GridViewCommandEventArgs e)        {            string tcId = e.CommandArgument.ToString();            if (e.CommandName == "go")            {                try                {                    TextBox tb = (TextBox)gv_tclist.BottomPagerRow.FindControl("inPageNum"); //跳转页码输入框                    int num = Int32.Parse(tb.Text);                    GridViewPageEventArgs ea = new GridViewPageEventArgs(num - 1);                    gv_tclist_PageIndexChanging(null, ea); //GridView分页事件                }                catch { }            }                    }

RowCommand 控件内按钮事件触发激活；

我们的模版中分页跳转按钮的CommandName="go",所以加入e.CommandName == "go"来区别不同的按钮
