用Table实现GridView控件功能,很多时候大家都是用微软提供的控件,但有时候需要自己写的时候又不知道从哪里写起,这里讲的是用最简单的控件实现微软自带的强大控件功能,当然这里的需求并不是复杂的!
前台代码:
- <%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="service.aspx.cs" Inherits="service" Title="Untitled Page" %>
- <asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
- <table style="width: 100%">
- <tr>
- <td style="text-align: right">
- 員工姓名:<asp:TextBox ID="tb_name" runat="server"></asp:TextBox></td>
- <td style="text-align: right">
- 身份證號:<asp:TextBox ID="tb_idcard" runat="server"></asp:TextBox></td>
- <td>
- <asp:Button ID="BT_Add" runat="server" OnClick="BT_Add_Click" Text="增加" /></td>
- </tr>
- <tr>
- <td colspan="3">
- <asp:Table ID="Table1" runat="server" style="text-align: left" BackColor="#C0C0FF" BorderColor="Black" BorderStyle="None" GridLines="Horizontal" Width="100%">
- </asp:Table>
- </td>
- </tr>
- <tr>
- <td colspan="3" style="text-align: right;">
- <asp:Button ID="bt_one" runat="server" Text="第一页" OnClick="bt_one_Click" />
- <asp:Button ID="bt_up" runat="server" Text="上一页" OnClick="bt_up_Click" />
- <asp:Button ID="bt_next" runat="server" Text="下一页" OnClick="bt_next_Click" />
- <asp:Button ID="bt_last" runat="server" Text="最后页" />
-
- 共
- <asp:Label ID="lb_count" runat="server" Text="" style="font-weight: bold; color: #0000ff; text-decoration: none"></asp:Label> 页
- </td>
- </tr>
- </table>
- <input id="h_pg" type="hidden" runat="server" />
- <input id="hf1" type="hidden" runat="server" />
