RadPanelBar for ASP.NET AJAX is the successor of RadPanelBar for ASP.NET. The next generation of RadControls is built entirely on top of ASP.NET AJAX, utilizing its common client-side framework and programming model. RadControls for ASP.NET AJAX introduce a number of new features and performance optimizations, which are hard or impossible to implement in the regular ASP.NET suite. The integration and API models of the controls are also better, due to the common framework they share (RadControls for ASP.NET AJAX are shipped as a single assembly - Telerik.Web.UI.dll.) It is important to note that this new generation of RadControls will work only on ASP.NET 2.0 and 3.5 because of the underlying ASP.NET AJAX framework.
Although there are a lot of new features in RadPanelBar for ASP.NET AJAX some of the functionality from the “classic” ASP.NET version is still the same. The forum threads in the RadPanelBar for ASP.NET forum are still relevant if they are in the following areas:
- DesignTime work with the control
- Server-side object model and event handling
