Multiview doesn't keep selected page during postback inside wrapped panel

Hi everyone,

I am developing a module for dotnetnuke;

In my ascx file, I have something similar to this:

<asp:panel>
    <asp:btn1>
    <asp:btn2>
    <asp:multiview>
 
    <view1>
    <controls with autopostBack />
    </view>
 
    <view2>
       </view>
       </multiview>
</panel>

On page.init, I use ajax.wrapupdatepanelcontrol on the panel; using btn1 and btn2, I select one of the views.

The problem is that, when I trigger another control, the currently selected view is reset, as if the selected view index is not mantained across postbakcs; obvusly, not wrapping the panel, everything works fine.

Is there an option or something to keep the selected page "automatically"?

The solution that comes to my mind is:

1 - save somewhere the selectedViewIndex;
2 - at each postBack, during pageLoad, check the stored value and set the activeView

Just would like to know if there's some better solution..

Thank you in advance,

Alberto

[EDIT]

For now, I solved that way..

when I activate a specific view, i also store its index in a a viewstate variable; than, during pageLoad, I check the value and re-set the multiview with the correct viewindex

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 multiView.ActiveViewIndex = ViewState("MyVar")
End Sub

protected sub selectView(byval index as int)
   multiView.ActiveViewIndex = index
   ViewState("MyVar") = index
end sub
