IQueryable isn't an IList or an IListSource, so that seems to be the problem. > var result = > from r in context.users > where r.UserName.Contains(userName) > select r; > > return result.ToList(); > > however this can be successfully bound to any datasource. And you found the solution -- give it an IList. I'm not entirely sure what the problem is. What you're binding to wants an IList, so you give it one and it's happy. It doesn't want an IQueryable (or an IEnumerable), so don't do that... - Jon --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "DbLinq" group.
