TreeView控件

1.在TreeView控件中进行选择

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;namespace TreeView{ public partial class Form1 : Form { public Form1() { InitializeComponent(); treeView1.CheckBoxes = true; } private void RefreshChildNode(TreeNode treenode, bool ifchecked) { foreach (TreeNode node in treenode.Nodes) { node.Checked = ifchecked; if (node.Nodes.Count > 0) { RefreshChildNode(node, ifchecked); } } } private void treeView1_AfterCheck(object sender, TreeViewEventArgs e) { if (e.Action != TreeViewAction.Unknown) { if (e.Node.Nodes.Count > 0) { RefreshChildNode(e.Node, e.Node.Checked); } } } }} 

ListView三个主要属性View，Columns，Items

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;namespace ListView2{ public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { this.listView1.View = View.Details; this.listView1.Columns.Add("姓名", 50,HorizontalAlignment.Center); this.listView1.Columns.Add("性别",50,HorizontalAlignment.Center); this.listView1.Columns.Add("籍贯", 200,HorizontalAlignment.Center); this.listView1.Items.Add("曹操"); this.listView1.Items[0].SubItems.Add("男"); this.listView1.Items[0].SubItems.Add("魏国"); this.listView1.Items.Add("刘备"); this.listView1.Items[1].SubItems.Add("男"); this.listView1.Items[1].SubItems.Add("蜀国"); this.listView1.Items.Add("孙权"); this.listView1.Items[2].SubItems.Add("男"); this.listView1.Items[2].SubItems.Add("吴国"); } //private void listView1_DoubleClick(object sender, EventArgs e) //{ // ListViewItem item=this.listView1.SelectedItems[0]; // Person p = new Person(); // p.Name = item.Text; // p.Gender = item.SubItems[1].Text; // p.Address = item.SubItems[2].Text; // ShowPersonInfo frm = new ShowPersonInfo(p); // frm.Show(); //} private void btnUpdate_Click(object sender, EventArgs e) { ShowPersonInfo frm = new ShowPersonInfo(this.listView1); frm.Show(); } }}=========================================================using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;namespace ListView2{ public partial class ShowPersonInfo : Form { private ListView lv; int index; public ShowPersonInfo( ListView lv) { InitializeComponent(); this.lv = lv; } private void ShowPersonInfo_Load(object sender, EventArgs e) { //获取当前选中项 ListViewItem item=lv.SelectedItems[0]; //获取当前选中项的索引 index = lv.SelectedIndices[0]; txtName.Text = item.Text; txtGender.Text = item.SubItems[1].Text; txtAddress.Text = item.SubItems[2].Text; } private void btnOK_Click(object sender, EventArgs e) { ListViewItem item = new ListViewItem(); item.Text = txtName.Text; item.SubItems.Add(txtGender.Text); item.SubItems.Add(txtAddress.Text); lv.Items.Insert(index, item); lv.Items.RemoveAt(index + 1); } }}
