I\'m trying to get the simplest possible example of a Listview with subitems working. But this code:
private void button1_Click(object sender, EventArgs e) {
Try adding the item after adding a subitem:
ListViewItem lvi = new ListViewItem(strArr[i]); lvi.SubItems.Add("Ciao, Baby!"); listView1.Items.Add(lvi); listView1.Items[i].Group = listView1.Groups[0];
Hope this helps!
