My thanks to Aaron Bertrand, SQL Server MVP, for assisting me with finding
an answer to my problem from the microsoft.public.sqlserver.programming
group.
I was able to resolve this issue by using the Replace function within the
Text property of the Label itself.
<asp:Label ID="lblManagerMsg" runat="server" Font-Names="Tahoma"
Text='<%#REPLACE(Eval("message"),vbCrLf,"<br>") %>' />
