Help with Tabstrip Question

[Patirck Ige]

I have a tabstrip like below:-
My question is if i click the tab "About Us" or "Resources" and goes to the
relevant pages
For example if i click on the About us and it redirects to the page
default.aspx how can i retain the TABS
on the top and target the window below not to redirect o another page and
the TABS not appearing i want the
TABS to stay
I tried using the "MultiPage" but nothing much to it on how i can keep the
TABS on the top and target the pages i want below
What worked was actually using an iframe window but i don't want to do that
any ideas ..
Or maybe i'm missing something?

Also is it possible to disable the TABS for example i would like to disable
the AboutUs TAB from some usersand enable it for others etc..

<mytab:TabStrip runat="server" ID="tsHoriz" Orientation="Horizontal"
AutoPostback="true">
<mytab:Tab Text="About Us" ID="tabAbout" />
<mytab:TabSeparator />
<mytab:Tab Text="Resources" ID="tabResources" />
</mytab:TabStrip>

And in codebehind:-
Protected Sub myTabStrip_OnSelectedIndexChange(ByVal sender As Object,
ByVal e As EventArgs) Handles tsHoriz.SelectedIndexChange
Select Case tsHoriz.SelectedIndex
Case 0
Response.Redirect("default.aspx")
' break
Case 1
Response.Redirect("css_frame.aspx")
' break
End Select
End Sub
