Columns not bound to DetailsView get set to NULL on update

I've got a page with a DetailsView. It uses a SqlDataSource which itself
uses stored procedures for Select and Update.

I don't want the user to see some of the columns, but if I don't bind them
(or if I do bind them but set Visible=False), when the Update procedure is
called, the parameters corresponding to the columns that weren't bound to the
DetailsView are all null.

This can't be an uncommon scenario, so I guess I have missed something. Any
ideas?

There was no way for you to know it (except maybe by browsing through some
of the previous questions in this newsgroup before posting yours - always a
recommended practice) , but this is a classic asp newsgroup. ASP.Net bears
very little resemblance to classic ASP so, while you may be lucky enough to
find a dotnet-knowledgeable person here who can answer your question, you
can eliminate the luck factor by posting your question to a group where
those dotnet-knowledgeable people hang out. I suggest
microsoft.public.dotnet.framework.aspnet or the forums at www.asp.net.
