User control not loading

I've got a user control that I have created named ContentPane. The page is very simplistic yet it is not showing up on the page when the page loads. I've tried to add the control to the page using the designer, and at run-time and I have no luck either way. I have placed some code in the page_load of the control to add a label to the control and I set a break point there. The event fires, and everything looks fine, but it does not get rendered. I'll include the code that I am using for the user control. I think it is pretty funny that my content pane won't show any content. It's kind of ironic.

User control Html:
<%@ Control Language="vb" AutoEventWireup="false" Codebehind="ContentPane.ascx.vb" Inherits="PeCON.PresentationLayer.ContentPane" TargetSchema="http://schemas.microsoft.com/intellisense/ie5" %>
<div align="center" class="ContentPane" id="divContent" runat="server">
      <img class="ContainerTopLeft" src="images\cont-tl.gif">
      <img class="ContainerTopRight" src="images\cont-tr.gif">
      <img class="ContainerBottomLeft" src="images\cont-bl.gif">
      <img class="ContainerBottomRight" src="images\cont-br.gif">
      
      Hello!!!!!!
</div>


User control code-behind:
Imports System.Web.UI
Imports System.Web.UI.WebControls

Namespace PresentationLayer
    Public Class ContentPane
        Inherits System.Web.UI.UserControl

#Region " Web Form Designer Generated Code "

        'This call is required by the Web Form Designer.
        <System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()

        End Sub
        Protected WithEvents divContent As System.Web.UI.HtmlControls.HtmlGenericControl

        'NOTE: The following placeholder declaration is required by the Web Form Designer.
        'Do not delete or move it.
        Private designerPlaceholderDeclaration As System.Object

        Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init
            'CODEGEN: This method call is required by the Web Form Designer
            'Do not modify it using the code editor.
            InitializeComponent()
        End Sub

#End Region

        Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
            'Put user code to initialize the page here
            Dim requestValues As New Label

            For Each name As String In Request.ServerVariables
                requestValues.Text += name & " = " & Request.ServerVariables(name) & "<BR>"
            Next

            divContent.Controls.Add(requestValues)
        End Sub

        Public Overrides ReadOnly Property Controls() As ControlCollection
            Get
                Return divContent.Controls
            End Get
        End Property
    End Class
End Namespace

Nevermind. I found that overriding the Controls property was creating problems. When I changed it to not override the controls property of the base class, it worked. Here is my solution.

        Public ReadOnly Property Content() As ControlCollection
            Get
                Return divContent.Controls
            End Get
        End Property
