I tried to play around with .Any() but haven't been successful.</p> <p>I would rather not iterate through using foreach and would rather stick w/ LINQ</p> <p>Any help is much appreciated</p>

    1. COI would like to control what the element is if it doesn't exist. For instance false or string.Empty if there's nothing in the .xml config file for that property/element.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
