This control does not support individual row data binding at the moment.  This is something that has been requested before and is already on the possible list of enhancement requests.  As for where the data comes from, it would not matter.  Business objects are ignorant of where the data comes from.

How could I modify ThemedDetailWindow so that it supports data binding to BO? I would think information come from data source like database or XML most of the time. Data retrieval usually done va BO.

Thank you

The ThemedDetailWindow is a control that can be used to show a specific set of details about an object.  A perfect example would be within the activation client (StrataFrame Menu -> License Information).  It is the control that displays on the first page of the wizard to show you details about your license file.  You can use it by adding items to display to the collection.  You then have to programmatically set the value of each of the items that you add.
