SelectedIndexCh anged event doesn't fire for Listbox or DropdownList

Yes, Autopostback is true, and it doesn't make an iota of difference at all.

HTML snippet and code (behind) snippet is as below:

<asp:dropdownli st id="ddlLoginTyp e" runat="server" Width="163px"
AutoPostBack="T rue"></asp:dropdownlis t>

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles MyBase.Load
If Not Me.Page.IsPostB ack Then
Me.ddlLoginType .Items.Add("Cus tomers")
Me.ddlLoginType .Items.Add("Sal es Rep")
Me.ddlLoginType .Items.Add("Adm in")

End If
End Sub

Private Sub ddlLoginType_Se lectedIndexChan ged(ByVal sender As Object, ByVal
e As System.EventArg s) Handles ddlLoginType.Se lectedIndexChan ged

....

End sub

I have changed the DDL to a Listbox and the same problem.
SelectedIndexCh anged event never ever fires!

Any idea?

I originally had the <form id="form1" runat="server"> and its associated
<form/> tag around the outside the body tag.

Once I place them inside the body tag, everything seemed to work.
