ASP.NET中的GridView控件功能基本实现

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.Data;

namespace 项目
{
    public partial class GridView : System.Web.UI.Page
    {
        SqlConnection sqlcon;//声明打开数据库连接字段
        string strCon = " Data Source=LENOVO-20110914;Initial Catalog=MyTest;Persist Security Info=True;User ID=sa;Password=11111";//

连接字符串
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                bind();
            }
        }
        //绑定GridView
        public void bind()
        {
            string sqlstr = "select  * from T_Student";//定义字符串Sqlstr并初始化 “在T_Student表中查询所有”
            sqlcon = new SqlConnection(strCon);//实例化连接对象
            SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);//定义适配器
            DataSet myds = new DataSet();//开辟内存空间
            sqlcon.Open();//打开数据库
            myda.Fill(myds, "T_Student");//把表填到缓存
            GridView1.DataSource = myds;//读取缓存里的表
        }
    }
}
