Test page

In a page containing a DropDownList, the following code

protected void Page_Load(object sender, EventArgs e)
{
  if (IsPostBack)
    return;

  for (int i = 1; i < 13; i++)
  {
    ListItem item = new
ListItem(CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(i),
i.ToString());
    item.Attributes.Add("title", "tooltip of " + i.ToString());
    DropDownList1.Items.Add(item);
  }
}

causes an exception to be thrown during the page opening. After removing the
Attributes.Add call, the example works.

The exception thrown is:
System.Runtime.Serialization.SerializationException: Type
System.Web.UI.StateBag is not marked as Serializable.
