一个功能，在ListView中的ListBoxItem控件上实现右键菜单关闭选项，将该ListBoxItem从ListView中删除。
利用 RoutedCommand类创建Command命令，MSDN上将其定义为一个实现 ICommand 并在元素树之内进行路由的命令。
C#代码：
private RoutedCommand closeCmd = new RoutedCommand("Clear", typeof(MainWindow));
private void ListBoxItem_MouseRightButtonUp(object sender,MouseButtonEventArgs e)
{
ListBoxItem data = new ListBoxItem();
data = (ListBoxItem)sender;
MenuItem close = new MenuItem();
close.Header = "删除";
//声明Mycommand实例
close.Command = closeCmd;
closeCmd.InputGestures.Add(new KeyGesture(Key.D, ModifierKeys.Alt)); //添加快捷键
close.CommandTarget = data; //命令作用目标
CommandBinding cb = new CommandBinding();
cb.Command = closeCmd;
cb.CanExecute += cb_CanExecute;
cb.Executed += cb_Executed;
data.CommandBindings.Add(cb);
data.ContextMenu = new ContextMenu();
data.ContextMenu.Items.Add(close);
data.ContextMenu.IsOpen = true;
}
private void cb_Executed(object sender, ExecutedRoutedEventArgs e)
{
ListBoxItem obj =(ListBoxItem)sender;
this.listView.Items.Remove(obj);
e.Handled = true;
}
private void cb_CanExecute(object sender, CanExecuteRoutedEventArgs e)
{
e.CanExecute = true;
e.Handled = true;
}
Command的其他实现方式可根据情况选择使用，这种实现方式方便于对UI界面中的元素进行操作。
