Templated User Controls

[gchq]

Hi there

I'm attempting to get a Templated User control to work, but for some reason the Template teg

[CODE=html]

<asp:PlaceHolde r ID="PlaceHolder 1" runat="server">

<DivTemplate>

<asp:Panel ID="Panel1" runat="server" Width="200" Height="300"></asp:Panel>

</DivTemplate>
</asp:PlaceHolder >

[/CODE]

Is not being recognised

Here is the code behind

[CODE=vbnet]

Imports System.Componen tModel


<ParseChildren( True)> _
<PersistChildre n(False)> _
Partial Public Class Secure_Admin_Ex pandingPanel

Inherits System.Web.UI.U serControl
Implements INamingContaine r
Private _DivTemplate As ITemplate = Nothing
Public HeaderText As String = "Header Text"
Public HeaderLabel As String = "Open"




Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArg s) Handles Me.Load
Header_Label.Te xt = HeaderLabel
Header_Text.Inn erHtml = HeaderText
CollapsiblePane lExtender1.Targ etControlID = "PanelHidde n"
CollapsiblePane lExtender1.Expa ndControlID = "Header1"
CollapsiblePane lExtender1.Coll apseControlID = "Header1"
CollapsiblePane lExtender1.Coll apsed = True
CollapsiblePane lExtender1.Imag eControlID = "Image1"
CollapsiblePane lExtender1.Coll apsedImage = "~\Images\plus. gif"
CollapsiblePane lExtender1.Expa ndedImage = "~\Images\minus .gif"
CollapsiblePane lExtender1.Text LabelID = "Header_Lab el"
CollapsiblePane lExtender1.Coll apsedText = "Display"
CollapsiblePane lExtender1.Expa ndedText = "Hide"
CollapsiblePane lExtender1.Coll apsedSize = 0
CollapsiblePane lExtender1.Expa ndedSize = 300
CollapsiblePane lExtender1.Scro llContents = True
End Sub



<PersistenceMod e(PersistenceMo de.InnerPropert y), TemplateContain er(GetType(Temp lateControl))> _
Public Property DivTemplate() As ITemplate
Get
Return _DivTemplate
End Get
Set(ByVal value As ITemplate)
_DivTemplate = value
End Set
End Property

Protected Overrides Sub OnInit(ByVal e As EventArgs)
MyBase.OnInit(e )
If _DivTemplate IsNot Nothing Then
_DivTemplate.In stantiateIn(Div Template)
End If

End Sub


End Class

[/CODE]

Any ideas where this might be going wrong?

Thanks
