try
{
conn.Open();
SqlDataAdapter sda = new SqlDataAdapter("select 姓名年龄等 from xsb where ID=点击获取的学生ID", conn);
DataSet ds = new DataSet();
sda.Fill(ds); this.listView1.Columns.Add("xh", 80, HorizontalAlignment.Center);
this.listView1.Columns.Add("姓名", 60, HorizontalAlignment.Center);//增加列标题
listView1.View = View.Details;
listView1.GridLines = true;//显示网格线。。
string[] str = new string[2];
foreach (DataRow row in ds.Tables[0].Rows)
{
str[0] = row["学号"].ToString();
str[1] = row["xm"].ToString();
ListViewItem item = new ListViewItem(str, 0);
listView1.Items.Add(item);
}
}
catch (Exception er)
{
MessageBox.Show(er.ToString());
conn.Close();
}
item.OnItemDoubleClick += new ItemDoubleClickEvent(item_OnItemDoubleClick);给你的ListBox中每个Item添加双击事件
