ListView用法

winform中ListView的用法

首先定义字头： this.listView1.Clear();
              ColumnHeader ch = new ColumnHeader();
            ch.Text = "URL";
            ch.Width = 200;
            ColumnHeader ch1 = new ColumnHeader();
            ch1.Text = "QQ";
            ch1.Width = 150;
            ColumnHeader ch2 = new ColumnHeader();
            ch2.Text = "Email";
            ch2.Width = 200;
            ColumnHeader ch3 = new ColumnHeader();
            ch2.Width = 200;

  将每列的开头绑定到ListView控件里面

  listView1.Columns.AddRange(new ColumnHeader[] { ch, ch1, ch2, ch3 });

 listView1.View = View.Details;

然后将数据列表绑定到控件：

定义个WebSiteInfo对象，里面包含WebSite，QQ，Email三个属性。

List<WebSiteInfo> list = new List<WebSiteInfo>();

给list赋值，然后将list绑定到ListView控件

 if (websiteinfo.Count() > 0)
            {
                foreach (var item in websiteinfo)
                {
                    ListViewItem lvi = new ListViewItem(new string[] { item.WebSite, item.QQ, item.Email }, -1);
                    listView1.Items.Add(lvi);
                }
            }

ListView选中行：

选中了几行：int i=listView1.SelectedItems.Count;

以下都是只选中了一行，多行的

 foreach (System.Windows.Forms.ListViewItem item in listView1.SelectedItems)
            {

            }

即可

选中的是第几行：  int index =listView1.SelectedItems[0].Index;

选中行的内容：该行第n列的数据： string txt= listView1.SelectedItems[0].SubItems[n].Text;

 删除选中的行：listView1.SelectedItems[0].Remove();
