Views in all versions of SQL Server are updatable (can be the target of
UPDATE, DELETE, or INSERT statements), as long as the modification
affects only one of the base tables referenced by the view.

You'll either have to use the ObjectDataSource with a business object
that can run multiple update statements on the base tables
or
modify your view with instead of triggers so that your single update
command would work from your SqlDataSource.

There might be other ways of updating a view with ADO.NET that some
other posters in this newsgroup might suggest.
