In fact I did end up using the in-line javascript and it works just fine.
The only minor drawbacks are that the screen goes blank on some systems but
only while the message is displayed, there is no flexibility is the dialog
title, the text in the message cannot really be formated, and there is
always a "beep" when the message is displayed. Still, it is a relatively
simple solution and it works consistently.

Sure, it's inline javascript. I think, he didn't mention that it must
be from the codebehind.

In addition to example by Mark, this can be done using public
variables as

vb.net
-----------------
Protected Dim x As Integer = 2
Protected Dim y As Integer = 3
-----------------

aspx
-----------------
if (<%=x%>==2 && <%=y%>==3)
alert("message");
-----------------

I think it should work as expected.

You can think about using Web2.0/ASP.NET way by implementing
ModalPopupExtender. The ModalPopup extender allows to display a free
designed "popup" in a similar manner which prevents the user from
interacting with the rest of the page. The popup can be shown via
server in code behind and on the client in script. It can be designed
in any way and you can have any title and no beep would occurred. This
would not require any big changes in code, but in application
configuration (you would need to download and include
AjaxControlToolkit and setup it in the web.config file. More about
ModalPopupExtender and AjaxControlToolkit you can find here
