We've had some feedback about our LinqServerModeDataSource not
supporting editing out of the box. (Suggestion
S19363 talks
about this rather tersely, mainly since it's constructed as a memo to
ourselves.)
Since there's been a few, er, discussions related to data sources on
this blog recently, I though I'd give you all a heads-up that we've
now added support for editing via this class with Linq2Sql sources and
it will be available in version 2008.2, the next major release.
If you are interested in participating in the beta for this support,
please track the above-mentioned issue. We'll get in touch with the
trackers once we're ready for someone to bash on it.
Until then, this knowledgebase article
(K18092)
describes a workaround.
