I'm trying to follow the demo shown here but when I run it as is I receive the following:
However, if I just select a subset and call ToList() on it, it doesn't throw the error.
Is there a new demo that shows the latest way of binding with EF? I will be using all the paging, filtering, sorting and grouping features.
Regards.
[NotSupportedException: Data binding directly to a store query (DbSet, DbQuery, DbSqlQuery, DbRawSqlQuery) is not supported. Instead populate a DbSet with data, for example by calling Load on the DbSet, and then bind to local data. For WPF bind to DbSet.Local. For WinForms bind to DbSet.Local.ToBindingList().]
