c# ListView 簡單操作

1. 添加數據

　　　　　　　listView1.Items.Clear();
            for (int i = 0; i < 50; i++)
            {
                ListViewItem lv = new ListViewItem();
                lv.Text = "new " + i;
                lv.SubItems.Add("feeder " + i);
                listView1.Items.Add(lv);
            }

2.獲取選擇項的事件

        private void listView1_SelectedIndexChanged(object sender, EventArgs e)
        {
            if (listView1.SelectedIndices != null && listView1.SelectedIndices.Count > 0)
            {
                ListView.SelectedIndexCollection c = listView1.SelectedIndices;
                clickname = listView1.Items[c[0]].SubItems[1].Text;
            }
        }

3.移除某行

        string clickname;
        private void button1_Click_1(object sender, EventArgs e)
        {
            if (clickname != "")
            {
                for (int i = 0; i < listView1.Items.Count; i++)
                {
                    if (listView1.Items[i].SubItems[1].Text == clickname)
                    {
                        //ncAndIp.Remove(clickname);
                        listView1.Items[i].Remove();
                        clickname = "";
                        break;
                    }
                }
            }
        }

4.遍歷並查找某項是否存在, 若存在高亮選擇

        private void button3_Click_1(object sender, EventArgs e)
        {
            string txt = textBox3.Text.Trim();
            if (txt != "")
            {
                for (int i = 0; i < listView1.Items.Count; i++)
                {
                    if (listView1.Items[i].SubItems[1].Text == txt || listView1.Items[i].SubItems[0].Text == txt)
                    {
                        //獲得焦點, 方便選擇效果
                        listView1.Focus();
                        //選擇該行
                        listView1.Items[i].Selected = true;
                        //滾動條滾到選擇行
                        listView1.EnsureVisible(i);
                        //在失去焦點的時候依然有選擇效果
                        //listView1.HideSelection = false;
                        break;
                    }
                }
            }
        }
