Hi,
I have a web application that collects data. The page is localized and
displayed in multiple languages including Chinese and Japanese. However I do
not want the users to type any DBCS characters in the input fields. Is there
any way to prevent the users from entering DBCS characters without writing a
ton of code on the server side?
Thanks in advance.

What exactly is a DBCS character in your case? Typing can never be prevented
anyway ;-)

You could use ASP.NET regular expression validators to exclude certain
characters, but you'll need tons of them.
