EnableFilter selectively enable the filter which is globally disabled. Enabling a globally disabled filter will apply only to that DbContext and it will not affect any other DbContext instances.
Conditionally Enabling Filters
Filters can also be enabled conditionally and you will even need to define those conditions along with your filter definition.
modelBuilder.Filter("BlogEntryFilter", (BlogEntry b, Guid accountID) => (b.AccountID == accountID), () => GetPersonIDFromPrincipal(Thread.CurrentPrincipal)); modelBuilder.EnableFilter("BlogEntryFilter", () => !UserIsAdmin(Thread.CurrentPrincipal));
In this example, a filter is defined on BlogEntry records to restrict only the current AccountID. But the filter will only be enabled if the user is not an Admin user.
