ListView显示列表，双击ListView里任意一行信息,出现一个可以修改的窗口

1、建立窗体Form1,并放一ListView控件

２、 /// <summary>
/// 执行SQL查询，显示到ListView中
/// </summary>
private void AddData()
{
//由于这里只做演示，数据就手动添加了
ListViewItem newItem1 = new ListViewItem(new string[] { "刘德华", "男", "未知", "汉族", "艺人" });
this.listView1.Items.Add(newItem1);
ListViewItem newItem2 = new ListViewItem(new string[] { "乖老鼠", "男", "100", "汉族", "程序员" });
this.listView1.Items.Add(newItem2);
ListViewItem newItem3 = new ListViewItem(new string[] { "高圆圆", "女", "未知", "不详", "乖老鼠的老婆" });
this.listView1.Items.Add(newItem3);
}
3、 listView1_ItemActivate事件

private void listView1_ItemActivate(object sender, EventArgs e)
{
if (listView1.SelectedItems[0].Index != -1)
{
ListViewItem oldItem = listView1.SelectedItems[0];
Form2 ff = new Form2(oldItem); //将这一行ListViewItem作为参数传给另外一个窗体
if (ff.ShowDialog() == DialogResult.OK)//如果被修改，刷新listView1
{
listView1.Refresh();
}
}

}

4、在Form1的load事件增加

AddData();

5、增加一窗体Form2

6、 定义变量　ListViewItem oldItem;

７、重写构造函数

　　public Form2(ListViewItem listItem)
{
InitializeComponent();
oldItem = listItem;
this.textBox1.Text = oldItem.SubItems[0].Text;
this.textBox2.Text = oldItem.SubItems[1].Text;
this.textBox3.Text = oldItem.SubItems[2].Text;
this.textBox4.Text = oldItem.SubItems[3].Text;
this.textBox5.Text = oldItem.SubItems[4].Text;
}

８、增加一button

private void button1_Click(object sender, EventArgs e)
{
oldItem.SubItems[0].Text = this.textBox1.Text.Trim();
oldItem.SubItems[1].Text = this.textBox2.Text.Trim();
oldItem.SubItems[2].Text = this.textBox3.Text.Trim();
oldItem.SubItems[3].Text = this.textBox4.Text.Trim();
oldItem.SubItems[4].Text = this.textBox5.Text.Trim();
this.DialogResult = DialogResult.OK;

}
