    1. COEven with this it won't work because there's no such property as `d1`. Also I think the correct `DataContext` binding will be `{Binding Source={StaticResource DeviceInterface}}` for your example.

    2. COAh, yeah. I think he wants results.Count. The DataContext should work as it is above.

    3. CONot until he implements `INPC` on top of `results` which is kinda what i said in my own answer :) Also I noticed he has no parameterless constructor for DeviceInterface so he can't do it in xaml like your example suggests without adding a new constructor

Guidance
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.

SQuiL has stopped working due to an internal error.

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