DynamicData: Database Based Permissions - Part 4

**** UPDATED ****

  1. Part 1 - Create the database tables.
  2. Part 2 - Add a User Interface to modify the permissions.
  3. Part 3 - User Marcin's InMemoryMetadataProvider to add the database based permissions to the Metadata at runtime.
  4. Part 4 - Add components from A DynamicData Attribute Based Permission Solution using User Roles to consume the database based metadata.
  5. Part 5 - Oops! Table Names with Spaces in them and Pluralization. 

Attribute Based Permissions added to Consume the Databased Based Metadata

I've added all the attribute based permissions login from my previous series A DynamicData Attribute Based Permission Solution using User Roles and zipped up the finished project files.

Here are the project files for Visual Studio 2008 with database in SQL Server 2005 and 2008, I've updated both downloads to use DynamicDataExtensions see below and to fix a small bug see Part 3 updates in bold.

Download for SQL server 2005

Download for SQL Server 2008

Note: I must emphasize that when you update the Table or Column attributes tables that the application MUST be restarted, see Marcin Dobosz's Dynamic Data samples: Custom metadata providers article on his blog under the section Truly dynamic metadata.

The user names and passwords:

Are now shown on the Login screen.

Yes the password is password, I know it's not good practice but it's only for demo  purposes.

Other changes I'm now making use of the DynamicDataExtensions (soon to be renamed DynamicDataFutures) and in particular the following FieldTemplates Enumeration.ascx & Enumeration_Edit.ascx instead of my own ColumnPermissions and TablePermissions. Further to the above I've added more users (see login page) and added more permissions to table and columns.

Thanks to David Ebbo for the above suggestions.
