 public void SetSelectedListItem(ListBox lst, List<DBServerIPBind> source)
        {
            for (Int32 i = 0; i < source.Count; i++)
            {
                if (source[i].IsSelected)
                {
                    ListItem item = lst.Items.FindByValue(source[i].DataValueField);
                    if (!object.Equals(item,null))
                    {
                        item.Selected = true;
                    }
                }
            }
        }
