Events and Delegates

I'm having a problem getting an event to fire in a usercontrol, which initiates
a subroutine in the page where the usercontrol resides. When I execute the
page, I receive no errors, but I'm not getting the results I would expect. What
am I doing wrong? (I have omitted most excess code for breviaty)


<Code>
--Usercontrol (selectarea) codebehind
Public MustInherit Class SelectArea
Public Event MyEvent As MyEventDelegate
Public Delegate Sub MyEventDelegate(ByVal sender As System.Object, ByVal e
As System.EventArgs)
Sub btnSelectArea_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles btnSelectArea.Click
Dim anItem As DataListItem
Dim blnIsChecked As Boolean
Dim intCheckedArea As Integer
Dim colSelectedArea As ArrayList
Dim chkSelected As System.Web.UI.WebControls.CheckBox
colSelectedArea = New ArrayList()
For Each anItem In dlstActiveAreas.Items
chkSelected = anItem.FindControl("chkAreaChoice")
If chkSelected.Checked Then
intCheckedArea = dlstActiveAreas.DataKeys(anItem.ItemIndex)
colSelectedArea.Add(intCheckedArea)
End If
Next
RaiseEvent MyEvent(Me, e)
End Sub
End Class
---Page object (codebehind)
Public Class ViewAllBids
Inherits System.Web.UI.Page
Protected WithEvents lblMessage As System.Web.UI.WebControls.Label
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
Dim objMyUserControl As SelectArea
objMyUserControl = CType(LoadControl("UserControls/SelectArea.ascx"),
SelectArea)
AddHandler objMyUserControl.MyEvent, AddressOf ucSelectArea

End Sub
Private Sub ucSelectArea(ByVal sender As System.Object, ByVal e As
System.EventArgs)
lblMessage.Text = "btnSelectArea Clicked"
End Sub
End Class
</Code>

I figure, if this were working properly, I would see "btnSelectArea Clicked" in
the output on my webform.
Can anyone see what I've done wrong?
