generated user controls

[pierre hourdille via .NET 247]

Hi,

I have a problem generating user controls at runtime:

I declare in my aspx page :

Dim userGrp As groups = New groups
phUsers.Controls.Add(userGrp)
userGrp.inicializar(sGrupo)
---------------------------------

... where phUsers is a placeHoder.

in my user control I have a "inicializar" public function :

Public Sub inicializar(ByVal grupo As String)
lblTitulo.Text = grupo
End Sub
------------------------------------------

and this html code:
<asp:Label ID="lblTitulo" CssClass="titulo" Runat="server"></asp:Label>

when I try to acces to lblTituloUsers.text (a label declared as protected withevents in my user control)
I have a "Reference to object ... " bug.

How can I acces the controls in my user control ?

Thank you for a little help
Pierre
