That is a very rude and impolite approach at getting help on this site.

Try this,
protected void ListBox1_SelectedIndexChanged(object sender, EventArgs e) { _count++; _items = new string[_count]; if (Session["Items"]!=null) { _items = Session["Items"]; } _items[_count - 1] = ListBox1.SelectedItem.Text.Trim(); Session["Items"] = _items; }Normal variable's values will be clear once the response is done. You can use Static variables but Static variable would share the values to other users also. But use a Session variable to maintain the items.

This may be cause of the problem. Every time you are initializing the array.So all items automatically erased.
