User Control Caching - Details

Sorry, maybe my previous question was rather confusing.

************************************
I have User Control:
[uc_button.ascx]

<%@ OutputCache Duration=60 VaryByparam="none" %>
<%@ Control Language="vb" ... %>
<asp:Button id="btnButtonCached" Text="Cached Button"
runat="server"></asp:Button>

************************************
I added this User Control to my WebForm and I want to add handler to the
button.

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load

Dim m As Control
m = LoadControl("uc_button.ascx")

PlaceHolder1.Controls.Add(m)

If TypeOf m Is uc_button Then
AddHandler CType(m, uc_button).btnButtonCached.Click, AddressOf btnKlik
Else
If TypeOf m Is PartialCachingControl Then
If Not CType(m, PartialCachingControl).CachedControl Is Nothing Then
AddHandler CType((CType(m, PartialCachingControl)).CachedControl,
uc_button).btnButtonCached.Click, AddressOf btnKlik
End If
End If
End If

End Sub



Problem is that after first postback, CachedControl is Nothing, so no
handler is added. What is wrong there?

Thanks!
