    1. COShow us your ViewModel Code and the Code of a single Season within the list. Have you set your DataContext correctly? Maybe you need to set the UpdateSourceTrigger to "PropertyChanged". Also, Rate must not be null.

    2. COWhat is the actual problem? Does your list bind correctly? If so, can you see the value of Room.RoomRate?

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.
