在ASP.NET中,要在单击按钮时将行添加到表中,可以按照以下步骤进行操作:
以下是一个示例代码,演示如何在ASP.NET中实现将行添加到表中的功能:
前端页面(ASPX文件):
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication1.Default" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Add Row to Table</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<label for="txtName">Name:</label>
<asp:TextBox ID="txtName" runat="server"></asp:TextBox>
<br />
<label for="txtAge">Age:</label>
<asp:TextBox ID="txtAge" runat="server"></asp:TextBox>
<br />
<asp:Button ID="btnAddRow" runat="server" Text="Add Row" OnClick="btnAddRow_Click" />
</div>
</form>
</body>
</html>
后端代码(CodeBehind文件):
using System;
using System.Configuration;
using System.Data.SqlClient;
namespace WebApplication1
{
public partial class Default : System.Web.UI.Page
{
protected void btnAddRow_Click(object sender, EventArgs e)
{
string name = txtName.Text;
int age = Convert.ToInt32(txtAge.Text);
string connectionString = ConfigurationManager.ConnectionStrings["YourConnectionString"].ConnectionString;
using (SqlConnection connection = new SqlConnection(connectionString))
{
string query = "INSERT INTO YourTable (Name, Age) VALUES (@Name, @Age)";
SqlCommand command = new SqlCommand(query, connection);
command.Parameters.AddWithValue("@Name", name);
command.Parameters.AddWithValue("@Age", age);
connection.Open();
command.ExecuteNonQuery();
}
// 清空输入字段
txtName.Text = string.Empty;
txtAge.Text = string.Empty;
// 显示成功消息
Response.Write("Row added successfully!");
}
}
}
请注意,上述示例代码中的数据库连接字符串(connectionString)和表名(YourTable)需要根据实际情况进行修改。
