Hi,
It looks like from your earlier thread you are essentially wanting a cascading combo box type of functionality within the web app views. You want values in one combo box to dynamically change based on the values in a different combo box. Am I understanding your scenario here correctly?
If so, unfortunately, we were not able to implement this type of functionality in time for the release of Access 2013. It is definitely a feature that we've thought about and can see scenarios for, however, time ran out for us so currently you cannot dynamically change the contents of one combo box based on another combo box within our Access web app views. I am hopeful we can implement something like this in the future.
Row level security is also another feature we currently do not have in our Access web apps. This is another feature I'd like to see us add into the product.
Since each Access web app is based directly on a SQL Server database, you can (assuming you have appropriate permissions) open the SQL database and do essentially whatever you want. That being said, you would essentially be completely in "unsupported" territory because our web apps are developed to have Access be your only design surface for creating/editing/deleting objects. If you step outside this space and make changes directly to the SQL objects and fields using SSMS, you could make it so Access can no longer understand the app and thus make it not editable by Access anymore. Make sense? So while it *might* be possible to implement row level security using SQL Server Management Studio on an Access 2013 web app, I don't have any idea how the app would function at runtime in the browser or in the designer using Access client.
Concerning my 2013 book, yes the first 600 pages of my new book are completely devoted to discussing our new Access 2013 web apps. I doubt any other competing book will cover this topic in greater detail than my book. I have the advantage of walking down the hall and asking each program manager, developer, and tester on the team, "Tell me everything about your feature." <evil laugh>
My new book should be rolling out in just a few weeks now. Personally, I believe it should have been out sooner (I finished writing in February) but the review and production process has taken much longer than I would have liked this time.
