private List lista = new List();

}

protected void lnkpickdate_Click(object sender, EventArgs e)

{

datepicker.Visible = true;

I can not make debugging on this project. Can you have a look on what I have sent you?

May I send you the files in order to have a look. I have already checked the list and the count. I have attached them. Do you have an email address?

2 points to check.

1. Line "lbReservations.Items.Add(reservationroom.DisplayName());". Please confirm here that "reservationroom.DisplayName has some valid values during runtime and not empty during assignment time

2. Also check the items count inside "lista"
