    1. CODoes the accepted answer not work in Monomac? I would think it should, and it's a lot simpler.

    2. COMonomac is C#, not obj-C. What I provided is just a (cleaned up) version of the answer in C#.

    3. COYou're providing a cleaned up version of the overly-complicated, more verbose, non-accepted Objective-C answer in C#. You can't make the same calls in C# that the accepted answer makes in Objective-C? That would only be roughly 4 lines of code (even in C#).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
