以上代码更改过，详见—原文，没有用到原文中所说的API进度条
listview添加右键菜单
1、插入控件 contextMenuStrip
2、在listview1的属性ContextMenuStrip中设置为刚插入的控件名称
3、写listview1事件 MouseClick
private void listView1_MouseClick(object sender, MouseEventArgs e)
{
//按鼠标右键
if (e.Button == MouseButtons.Right)
{
if (this.listView1.SelectedItems.Count > 0)
{
this.contextMenuStrip1.Show(this, e.Location);
}
else
{
this.contextMenuStrip1.Hide();
}
}
}
4、再增加contextMenuStrip的属性集合，编写单击contextMenuStrip控件的集合项事件。
- 使两个listview的列宽相等
for (int i = 0; i < listView2.Columns.Count; i++)
{
listView1.Columns[i].Width = listView2.Columns[i].Width;
}
