Answer 1

Hi @MiPakTeh , Welcome to Microsoft Q&A.

The grouping of your button2 seems to be different from before. Is this what it should be?

The reason for the error is that in the previous code, I only considered the case where the number is a single character.

You can use Substring with TrimEnd and other methods to get all the numbers ahead, currently it supports 5 digits.

You just need to modify the code of listBox3_SelectedIndexChanged to:

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;
        string tmpString = item.Substring(0, 5);
        int index = int.Parse(tmpString.TrimEnd("Min=".ToCharArray()));
        for (int i = index * 12; i < ((index + 1) * 12); i++)
        {
            string listbox1item = listBox2.Items[i].ToString();
            listBox4.Items.Add(listbox1item);
        }
    }
}

Best Regards,

Jiale
