ASP.NET中的GridView控件功能基本實現

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 項目
{
    public partial class GridView : System.Web.UI.Page
    {
        SqlConnection sqlcon;//聲明打開數據庫連接字段
        string strCon = " Data Source=LENOVO-20110914;Initial Catalog=MyTest;Persist Security Info=True;User ID=sa;Password=11111";//

連接字符串
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                bind();
            }
        }
        //綁定GridView
        public void bind()
        {
            string sqlstr = "select  * from T_Student";//定義字符串Sqlstr並初始化 “在T_Student表中查詢所有”
            sqlcon = new SqlConnection(strCon);//實例化連接對象
            SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);//定義適配器
            DataSet myds = new DataSet();//開闢內存空間
            sqlcon.Open();//打開數據庫
            myda.Fill(myds, "T_Student");//把表填到緩存
            GridView1.DataSource = myds;//讀取緩存裏的表
        }
    }
}
