本文介绍了如何在ASP.NET中使用GridView控件实现数据库表格数据的增删改功能。通过创建数据库表，设置GridView的编辑、删除按钮，并在后台处理C#代码，实现了表格数据的动态交互操作。

1、创建数据库表

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[Table1](
[ID] [int] IDENTITY(1,1) NOT NULL,
[Employees] [varchar](50) COLLATE Chinese_PRC_CI_AS NOT NULL,
[Position] [varchar](50) COLLATE Chinese_PRC_CI_AS NOT NULL,
[Team] [varchar](50) COLLATE Chinese_PRC_CI_AS NOT NULL,
CONSTRAINT [PK_Table1] PRIMARY KEY CLUSTERED
(
[ID] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

GO
SET ANSI_PADDING OFF

2、ASPX代码 <asp:GridView ID="GridViewEmployee" runat="server" AutoGenerateColumns="False" ShowFooter="True" onrowcancelingedit="GridViewEmployee_RowCancelingEdit" onrowediting="GridViewEmployee_RowEditing" onrowupdating="GridViewEmployee_RowUpdating" onrowdeleting="GridViewEmployee_RowDeleting"> <Columns> <asp:TemplateField HeaderText="Employee Name"> <EditItemTemplate> <asp:TextBox ID="TextBoxEditEmployee" runat="server" Text='<%# Bind("Employees") %>'/> </EditItemTemplate> <ItemTemplate> <asp:Label ID="LabelEmployee" runat="server" Text='<%# Bind("Employees") %>'/> </ItemTemplate> <FooterTemplate> <asp:TextBox ID="TextBoxEmployee" runat="server"/> </FooterTemplate> </asp:TemplateField > <asp:TemplateField HeaderText="Position"> <EditItemTemplate> <asp:TextBox ID="TextBoxEditPosition" runat="server" Text='<%# Bind("Position") %>'/> </EditItemTemplate> <ItemTemplate> <asp:Label ID="LabelPosition" runat="server" Text='<%# Bind("Position") %>'/> </ItemTemplate> <FooterTemplate> <asp:TextBox ID="TextBoxPosition" runat="server"/> </FooterTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Team Name"> <EditItemTemplate> <asp:TextBox ID="TextBoxEditTeam" runat="server" Text='<%# Bind("Team") %>'/> </EditItemTemplate> <ItemTemplate> <asp:Label ID="LabelTeam" runat="server" Text='<%# Bind("Team") %>'/> </ItemTemplate> <FooterTemplate> <asp:TextBox ID="TextBoxTeam" runat="server"/> </FooterTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Employee ID"> <ItemTemplate> <asp:Label ID="LabelID" runat="server" Text='<%# Bind("Id") %>'/> </ItemTemplate> <FooterTemplate> <asp:Button ID="Button1" runat="server" Text="增加" OnClick="Button1_Click" /> </FooterTemplate> </asp:TemplateField> <asp:CommandField ShowEditButton="True" ShowDeleteButton HeaderText="操作" /> </Columns> </asp:GridView>

3、后台C#代码：

protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack)
            {
                BindGridView();
            }
        }

        private string GetConnectionString()
        {
            //Where MyConsString is the connetion string that was set up in the web config file
