Hi @MiPakTeh , Welcome to Microsoft Q&A.

Note the difference between ASCII and int.

private void listBox3_SelectedIndexChanged(object sender, EventArgs e)
{
    listBox4.Items.Clear();
    string curItem = listBox3.SelectedItem.ToString().Trim().Replace(" ", "");

    var arr = curItem.Split('>').ToList();
    foreach (var item in arr)
    {
        if (item == "") return;
        int index = int.Parse(item[0].ToString());
        for (int i = index * 12; i < ((index + 1) * 12); i++)
        {
            string listbox1item = listBox2.Items[i].ToString();
            listBox4.Items.Add(listbox1item);
        }
    }
}
