The powerful Control Template and Styling mechanism of the forthcoming RadTreeView for Silverlight 2 will allow you to easily create a "bracket" view. The forthcoming CTP release of RadControls for Silverlight 2 (that will be live as soon as Microsoft launches the official Silverlight 2 Beta 2) will feature such an example in the QSF section. The screen-shot below gives you a short preview of what the lookless RadTreeView is all about.
Another example that will be demonstrated within the QSF section is a panelbar view of the tree control.
Along with its advanced layout mechanism RadTreeView harnesses the power of content-driven controls.
