Winform ListView 嵌入组合框、布尔、图片等复杂控件

一、Winform ListView 显示复杂控件示例

以下展示了两种实现思路方案。

1.1 方案一：ListView 结合组合框进行模拟编辑

基本思路

在界面上放置一个lisview和一个combobox，combobox平时是隐藏的。
点击listview，在点击位置的单元格上显示这个combobox
combobbox数据变更后，更新到listview

核心代码如：

    public partial class Form1 : Form{ListViewSubItem _cell;  // 被选中的单元格public Form1(){InitializeComponent();InitData();}void InitData(){// combobox comboBox1.Visible = false;this.comboBox1.Items.Add("科比");this.comboBox1.Items.Add("姚明");this.comboBox1.Items.Add("杜兰特");this.comboBox1.Items.Add("邓肯");// listviewlistView1.Columns.Add("第一列");listView1.Columns.Add("第二列");listView1.Columns.Add("第三列");var item = new ListViewItem(1.ToString());item.SubItems.Add("姚明");item.SubItems.Add("科比");listView1.Items.Add(item);item = new ListViewItem(2.ToString());item.SubItems.Add("邓肯");item.SubItems.Add("杜兰特");listView1.Items.Add(item);}// ListView 点击后在点击单位格位置处显示控件private void lv_MouseUp(object sender, MouseEventArgs e){// 将控件定位到点击单元格中var lvi = this.listView1.GetItemAt(e.X, e.Y);if (lvi != null){_cell = lvi.GetSubItemAt(e.X, e.Y);var n = lvi.SubItems.IndexOf(_cell);if (_cell != null && n>0){var rect = _cell.Bounds;rect.Y += 5;this.comboBox1.Visible = true;this.comboBox1.Bounds = rect;this.comboBox1.Text = _cell.Text;this.comboBox1.BringToFront();//this.comboBox1.Focus();return;}}this.comboBox1.Visible = false;}// 组合框数据变更后，将数据更新到单元格private void comboBox1_SelectedIndexChanged(object sender, EventArgs e){if (_cell != null){_cell.Text = comboBox1.Text;}}}

效果如：
在这里插入图片描述

1.2 方案二：自定义 ListView 和各种列

功能

嵌入下拉框列
嵌入色彩列
嵌入数字编辑列
嵌入布尔值列
嵌入图片列
点击标题列排序
行选择

使用代码

    public partial class Form2 : Form{public Form2(){InitializeComponent();InitListView();}public void InitListView(){this.lv.Columns.Add(new BaseColumnHeader("序号", 50));this.lv.Columns.Add(new BaseColumnHeader("可见", 50));this.lv.Columns.Add(new BaseColumnHeader("颜色", 60));this.lv.Columns.Add(new BaseColumnHeader("数值", 150));this.lv.Columns.Add(new BoolColumnHeader("布尔值", Resources.BulletTick, Resources.BulletCross, 100));this.lv.Columns.Add(new BaseColumnHeader("图片", 200));var r = new Random();for (int i = 0; i < 10; i++){lv.BeginUpdate();var b = r.Next(100) % 2 == 0 ? true : false;var item = new ListViewItemBase(i.ToString());var visibleCell = new ListViewControlSubItem();var colorCell = new ListViewControlSubItem();var numCell = new ListViewControlSubItem();var boolCell = new ListViewBoolSubItem(b);var imageCell = new ListViewImageSubItem(Resources.Cart);// comboxvar cmbVisible = new ComboBox();cmbVisible.Items.Add("是");cmbVisible.Items.Add("否");cmbVisible.SelectedIndex = 0;//cmbVisible.Focus();// color labelvar label = new Label();label.BackColor = Color.Green;label.Text = "";label.BorderStyle = BorderStyle.FixedSingle;label.MouseClick += new MouseEventHandler(bt_MouseClick);// number boxvar num = new NumericUpDown();num.Margin = new Padding(0);num.Minimum = new decimal(-999999999.0);num.Maximum = new decimal(999999999.0);num.Value = new decimal(i * 10);num.DecimalPlaces = 2;// controlslv.AddControlToSubItem(visibleCell, cmbVisible);lv.AddControlToSubItem(colorCell, label);lv.AddControlToSubItem(numCell, num);item.SubItems.Add(visibleCell);item.SubItems.Add(colorCell);item.SubItems.Add(numCell);item.SubItems.Add(boolCell);item.SubItems.Add(imageCell);lv.Items.Add(item);lv.EndUpdate();}           }// color boxvoid bt_MouseClick(object sender, MouseEventArgs e){Label lb = (Label)sender;colorDialog1.Color = lb.BackColor;if (colorDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK){lb.BackColor = colorDialog1.Color;}}// get selected item valuesprivate void button1_Click(object sender, EventArgs e){if (lv.SelectedIndices.Count == 0){MessageBox.Show("没有选择");return;}for (int j = 0; j < lv.SelectedIndices.Count; j++){// itemint i = lv.SelectedIndices[j];var itemName = lv.Items[i] as ListViewItemBase;var itemVisible = itemName.SubItems[1] as ListViewControlSubItem;var itemColor   = itemName.SubItems[2] as ListViewControlSubItem;var itemValue   = itemName.SubItems[3] as ListViewControlSubItem;// controlsComboBox cmbVisible = itemVisible.Control as ComboBox;Label lb = itemColor.Control as Label;var num = itemValue.Control as NumericUpDown;// valuesstring name = itemName.Text;Color color = lb.BackColor;string visible = cmbVisible.Text;double value = Convert.ToDouble((num).Value);MessageBox.Show(string.Format("{0},{1},{2},{3}", name, color.ToString(), visible, value));}}private void lv_SelectedIndexChanged(object sender, EventArgs e){var ids = lv.SelectedIndices;}}
