[Solved] Filter drop down menus are empty

[Ben]

Hi,
I'm binding to a ModelView and one of the Bound columns is bound to another entity (using EF4). Other columns filter fine, but this one column shows empty dropdowns instead of 'contains, 'starts with', etc...

Column 'Company Name' filters fine, but 'Customer Numbers' shows empty dropdown filters.

Any ideas?

ViewModel is created by select using following expression


public static Expression<Func<MasterContactCompany, MasterContactViewModel>> CreateMasterContactViewModelFromContactCompany()
        {
            return (o => new MasterContactViewModel
                         {
                             Id = o.MasterContact.Id,
                             CompanyName = o.Company.Name,
                             CustomerNumbers = o.Company.ContactCompanies
                                .Where(m => m.ContactID == o.ContactID && m.CompanyID == o.CompanyID)
                                .Select(m => m.CustomerNumber)
                                .Distinct()
                                .AsQueryable()
                         }
                   );
        }
