         24

and I also need to know on which one did I clicked from the listBox1. For example: I clicked on the '24' in the listBox1 and the value '24' will show in textBox1

Answer 1

Did you set these properties?

listBox1.DataSource = yourTable;
listBox1.DisplayMember = "Name";
listBox1.ValueMember = "ID";

In this way, your listbox will show the column name, but when you click an item you could get the value (ID) associated with that name

    private void ListBox1_SelectedValueChanged(object sender, EventArgs e)
    {
        if (listBox1.SelectedIndex != -1)
        {
            int personID = Convert.ToInt32(listBox1.SelectedValue.ToString());
            .......
        }
    }
