代码如下　

using System;

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 News_edit : System.Web.UI.Page
{
    public Socut myData = new Socut ();
    public DataSet ds = new DataSet();
    protected void Page_Load(object sender, EventArgs e)
    {
        string strID = Request["id"];
        ds = myData.GetDataSet("SELECT n_id,n_title,n_content FROM Socut_News WHERE n_id='" + strID + "'", 0,0, "dsTable");
        if (!Page.IsPostBack)//此句一定要加，否则无法更新
        {
            TextBox1.Text = ds.Tables["dsTable"].Rows[0][1].ToString();
            TextBox2.Text = ds.Tables["dsTable"].Rows[0][2].ToString();
        }

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        string strID = Request["id"];
        myData.GetExecuteNonQuery("UPDATE socut_news SET n_title='" + TextBox1.Text + "',n_content='" + TextBox2.Text + "' WHERE n_id='" + strID + "'");
        Label1.Text = "更新成功！";
    }
    protected void Button2_Click(object sender, EventArgs e)
    {
        string strID = Request["id"];
        myData.GetExecuteNonQuery("DELETE FROM socut_news WHERE n_id='" + strID + "'");
        Label1.Text = "删除成功！";
    }
}

摘自网易的一个教程，只是自己猜写了一个数据操作类，不用作者的组件，最后达到同样的效果．建议初学者去下载！
