更新ListView C#中的ListViewItem中的subItem的值(Winforms) [英] Updating the value of a subItem in a ListViewItem inside a listview c# (Winforms)

问题描述

我想更新ListViewItem中包含的ListviewItem中包含的数据. 我们的想法是当选择了列表视图的一排，我点击一个按钮，数据被更新.

I would like to update the data contained in a ListviewItem contained itself in a ListView. The idea is when a row of the listview is selected, I click on a button and the data is updated .

我有此代码:

ListView listView1 = new System.Windows.Forms.ListView();   
ListViewItem lv1 = new ListViewItem("me");    
lv1.SubItems.Add("my brother");    
listView1.Items.Add(lv1);

Button myB = new System.Windows.Forms.Button();

private void myB_Click(object sender, EventArgs e)
{
    listView1.SelectedItems[0]  ....... ;
}

我知道如何进一步访问以将我的兄弟"的值修改为我的妹妹".

I know how to go any further to acces to modify the value of "my brother" to "my sister".

提前谢谢.

推荐答案

检查是否选择了某些内容，然后访问SelectedItems中的第一个ListViewItem

Check if something is selected then access the first ListViewItem in the SelectedItems

if(listView1.SelectedItems != null)
{
   ListViewItem item = listView1.SelectedItems[0];
   item.SubItems[0].Text = "Sister";
}

这是MSDN上的引用 ListViewSubItem类

this is the reference on MSDN for ListViewSubItem class
