Well, I'm going to try to explain more clear (my english is very poor),

Well, I'm trying to create a little SilverLight Module for show Contents, but I don't want to lose the standar functionality because SilverLight is very new.

Well, In my index.ascx I have:

<% If user is Administrador %>

<td id="ContentPane" />

<% else %>

<td><asp:SilverLight></td>

<% end if %>

This rules ok, but I have the next problem, If one user click in login page (for identification), dotNetNuke don't change Tab, dotNetNuke show LoginControl and it don't show Modules added.

I need to know how dotNetNuke do this, because I need do this:

<% If user is Administrador or Show_Identification_Control or show_register_control %>

<td id="ContentPane" />

<% else %>

<td><asp:SilverLight></td>

<% end if %>

I hope you now understand me.

Best Regards and excuse for my English.
