    1. COI'm pretty sure you can't use a Visibility-Binding for a DataGridTextColumn out of the box, since it isn't in the visualtree and doesn't have a DataContext.

    2. COactually, you can, It works like a charm. +1 for decyclone. Alternatively, you can make your own DataGridTemplateColumns and use DataTriggers, but here it is easier to use decyclone's solution I think.

    3. CO@David: I've never gotten that to work without using an inherited datacontext (discussed here: http://stackoverflow.com/questions/502389/binding-in-a-wpf-data-grid-text-column). I tried this example and all I got was "System.Windows.Data Error: 2 : Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:(no path); DataItem=null; target element is 'DataGridTextColumn' (HashCode=39268741); target property is 'Visibility' (type 'Visibility')"

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).
