    1. COCoul dyou add the code of the TemplateType class? My guess is that it doesn't implement INotifyPropertyChanged.

    2. COI don't see where you are creating a "TemplateForPlan" object. You are declaring what it is, but you did not define one or create a visual element tree anywhere in that code. The binding in your label can only access element names in the same visual tree. Show more of the file in which you declared the Label. You need to actually instantiate a TemplateForPlan object in that same file in order to bind to it. And even then, in order for the binding to work you need to either implement a DependencyProperty or INotifyPropertyChanged.

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.
