Controls based on roles or logged in

How do I wrap code around a user control in order to indicate that it should only be displayed if the user has a certain role?

Same also for only displaying if a user is logged in?

I know how to register one and put it on the page, I just don't know how to do the if/else stuff.

thanks!

Two options imo.
1) use the provided control (asp:LoginView) and use the appropriate template
2) use a little bit of code (<asp:.... visible='<%# Page.User.IsAuthenticated%>' /> or <asp:.... visible='<%# Page.User.IsInRole("administrator")%>' />)

when I use that on a control:
Visible="<%# Page.User.IsInRole("administrator")%>"

I get an error: Parser Error Message: The server tag is not well formed.

<uc:RBox ID="RBox1" runat="server" Visible="<%# Page.User.IsInRole("administrator")%>" />

Isn't there a way to do multiple roles?

Or if the user is NOT in the role?

Well - you didn't copy the code as I gave you. Note the different quotation marks

Visible='<%# Page.User.IsInRole("administrator")%>'

Multiple roles:
Visible='<%# (Page.User.IsInRole("administrator") or Page.User.IsInRole("editor"))%>'

Not in a role (using C#)
Visible='<%# !Page.User.IsInRole("administrator")%>'

Not in a role (using VB.Net)
Visible='<%# Not Page.User.IsInRole("administrator")%>'

Ugh. I graded too soon.

this:
<uc:BannerAdvfn ID="Banner1" runat="server" visible='<%# Page.User.IsAuthenticated%>'  />

gives this error:
Compiler Error Message: BC30456: 'IsAuthenticated' is not a member of  'System.Security.Principal.IPrincipal'.

Well, even that doesn't seem to work with single or double quotes (it says I have to have double to match the rest of my control), or NOT or not NOT. It always displays whether logged in or not:

<uc:MenuAd ID="Menu2" runat="server" Visible="<%# Page.User.Identity.IsAuthenticated%>"/>

But that's okay. Someone else showed me how to define it in the page load... which works better for my purposes anyway.

thanks.


        If isLoggedIn Then ' defined above.....
            Me.Menu1.Visible = False
        Else
            Me.Menu2.Visible = False
        End If
