client-side maximum string length enforcement

When I was working with ASP/ADO, I would get the maximum string length
by querying the system tables inside the mssql database. It wasn't the
wisest thing to do, but it did let me determine the max string length
for each of my textboxes, which kept me from writing updates that
couldn't be successfully submitted because of strings that are too
long.
Now I have an ASP.NET client talking to a Web Service which gets it's
data out of a MS SQL Server database. I don't really have the luxury
of having the client ask the database how long it's strings are. So
what's the proper way to get the string maximum length from the DB out
to the client?
