<span style="color:#ff0000;">SelectCommand="SELECT * FROM [T_SERIES] WHERE SE_DELETE=FALSE ORDER BY SE_ORDER DESC" 要修改这一语句，表示显示SE_DELETE标记为false的项。</span>
<span style="color:#ff0000;"> CommandArgument='<%#Eval("se_id") %>' 用于参数的传递</span>
.aspx.cs代码如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.OleDb;
public partial class test : System.Web.UI.Page
{
string str_cnn = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=";
string str_sourcefile = "mdb\\EV.mdb";
OleDbConnection cnn;
OleDbCommand cmd;
OleDbDataReader datar;
string str_sql;
protected void Page_Load(object sender, EventArgs e)
{
}
protected void mycmd(object sender, CommandEventArgs e){
string str_conn = str_cnn + MapPath(str_sourcefile);
cnn = new OleDbConnection(str_conn);
cnn.Open();
str_sql = "update t_series set se_delete =true where " +
"se_id =" +<span style="color:#ff0000;"> e.CommandArgument.ToString();//接收参数！！！</span>
cmd = new OleDbCommand(str_sql, cnn);
cmd.ExecuteNonQuery();
cnn.Close();
<span style="color:#ff0000;">Listview1.DataBind();//数据控件内部按钮，执行完之后需要重新绑定一下数据控件的数据</span>
}
}
效果如下：
当点击确定时，此项被标记删除。
