Hi, for your latest KeyCode issue: KeyPreview property of form need to set as true. Check below link

Hi, You can use KeyUp or KeyDown event to delete. Try below code
private void ListView1_KeyUp(object sender, KeyEventArgs e)
{
    ListView ListViewControl = sender as ListView;
    if (e.KeyCode == Keys.Delete)
    {
        foreach (ListViewItem eachItem in ListViewControl.SelectedItems)
        {
            ListViewControl.Items.Remove(eachItem);
        }

    }
}

Hi,

You can do as shown in sample:
private void listView1_KeyDown(object sender, KeyEventArgs e)
{
    if (Keys.Delete == e.KeyCode)
    {
        foreach (ListViewItem listViewItem in ((ListView)sender).SelectedItems)
        {
            listViewItem.Remove();
        }
    }
}
