In my application I have a usercontrol called "base" with a panel
called "pnl1"; in "pnl1" I put my usercontrol.

Now I would like to have 2 possibilities: from "base" to load another
control called "ctl2" (and there's no problem) but I would like also
to load "ctl2" from "ctl1"!
The name of the control to load is "stored" into Session("activeCtl")

base.ascx Page_Load code:

Dim ctl As UserControl = New UserControl

ctl = LoadControl(Session("activeCtl") & ".ascx")
pnl1.Controls.Add(ctl)

The first time my Default.aspx set the value of Session("activeCtl").

ctl1.ascx: code put into a routine that accept a parameter called
"name" with the ascx name to load

Dim pnl1 As Panel

pnl1 = Me.Page.Parent.FindControl("pnl1")

Session("activeCtl") = name
pnl1.Controls.Clear()

Dim ctlChild As UserControl
ctlChild = Me.Page.LoadControl(name & ".ascx")

pnl1.Controls.Add(ctlChild )

also ctl2.ascx has an identical routine.

Then, coming back to explanation.
Application start: "base" is loaded
"base" loads "ctl1"
in "ctl1" there is a button that loads "ctl2"
in "ctl2" there is a button that loads "ctl1"

All seems that works fine... but if I try to click another button
(that execute normal code into control), the event doesn't fire.
Usercontrol is re-loaded another time. If I click another time the
button, the code is executed.

Why????

Sorry for my bad english... is a bit complicated to explain...
