.建立两个页面A、B
在web.config创建连接
A页面：在GridView里面实现数据库连接并显示出数据，在GridView里面添加超链HyperLinkField，并使之连接到B页面。用于将GridView的一行数据的信息显示到B页面中。（注意：在HyperLinkField属性的DataNavigateUrlFields 设置你的主键ID，比如DataNavigateUrlFields="StuId"）,

B页面:
using System;
using System.Data;
using System.Data.SqlClient;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class MemberManage_EditGInfo : System.Web.UI.Page
{
    SqlConnection sqlconn = new SqlConnection(ConfigurationManager.AppSettings["ConnectionString"]);
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            sqlconn.Open();//打开数据库连接
            string strid = Page.Request.QueryString["GoodsID"];//接收页面传值
            string sqlstr = "select * from tbPicture where PicId='" + strid + "'";//创建查询语句
            SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlconn);
            DataSet myds = new DataSet();
            myda.Fill(myds, "tbPicture");
            DataRowView mydrv = myds.Tables["tbPicture"].DefaultView[0];//创建表视图DataRowView
            txtGID.Text = Convert.ToString(mydrv.Row["PicId"]);
            txtGName.Text = Convert.ToString(mydrv.Row["PicName"]);
            txtGType.Text = Convert.ToString(mydrv.Row["PicType"]);
            txtGStore.Text = Convert.ToString(mydrv.Row["GoodsStock"]);
            txtGPrice.Text = Convert.ToString(mydrv.Row["SellNumber"]);
            txtGIntro.Text = Convert.ToString(mydrv.Row["PicName"]) + "…";
            iGPhoto.ImageUrl = Convert.ToString(mydrv.Row["PicPath"]);
        }
    }
}
