Autopostback e Listbox

[dwb]

Nel mio form ho alcune Listbox e, a seconda del valore selezionato, devo abilitare o no una textbox. Fino a quando ho un solo Listbox tutto funziona a meraviglia, ma appena ho inserito il secondo, sembra che questo modifichi il comportamento anche del primo.

Ecco il codice:

 protected void chkTrade_SelectedIndexChanged(object sender, EventArgs e)
        {
           if(chkTrade.SelectedValue=="SI")
            {
                txtTrade.Enabled = true;
            }
           else
            {
                txtTrade.Enabled = false;
            }
        }


        protected void chkEtoro_SelectedIndexChanged(object sender, EventArgs e)
        {
            if(chkEtoro.SelectedValue =="SI")
            {
                txtEtoro.Enabled = true;
            }
            else
            {
                txtEtoro.Enabled = false;
            }
        }

Come posso separare gli ambiti?

Stai attento a fare il bind DENTRO una If che sia solo al Not Postback

if (!IsPostBack)
{
 Bind_chkTrade(); // sub che effettua il bind della LB1
 Bind_chkEtoro(); // sub che effettua il bind della LB2
}

altrimenti al cambiamento di uno dei due, la pagina rifa' il bind e porta allo stato iniziale entrambe le LBox.

Posta tutto il codice, comunque. Il comportamento è anomalo.
