It is often necessary to customize the header of a RadPane.

How To: Display Hierarchical Data with Row Details (RadGridView for Silverlight)
The main goal of the Row Details feature is to let you present additional information about a row. This makes row details the perfect candidate for presenting hierarchical data. My sample uses two kinds of business objects – a football club and its players. As you might expect each club has some players. The master grid will show our clubs and when the user wants to see some additional information about a club he will be presented with the row details.
