Security for detail pages
It's important to secure your detail pages, because otherwise all users of Rhythm for Civics will have full access to your detail records. To secure your detail pages, you can use filters to restrict access. For example, you might only allow users to see application details associated with applications on which they are applicants.
To define a filter you can use either an expression group or a custom assembly. An expression group is a set of filter criteria that you define in the Portal configuration. Custom assemblies implement the IPortalFilter interface, which defines a method called AddFilter that you can use to define your filter criteria.
